The Architecture of the Roadside

By: Small Certainty

On December 31, 1959, a restaurant opened above the Autostrada del Sole near Fiorenzuola d'Arda, in northern Italy. Its glass-walled dining room stretched across the motorway between Parma and Piacenza, with vehicles passing beneath it in both directions. Motorists could leave the road, park on either side, and ascend to a restaurant from which they could watch other cars continuing their journeys. Above the building, the name PAVESI advertised the biscuit manufacturer responsible for its construction.

The architect, Angelo Bianchetti, called the building the Transatlantico, after the ocean liners whose horizontal profiles and elaborate accommodations had become emblems of sophisticated travel. The restaurant extended approximately seventy meters across the motorway. Its reinforced-concrete structure supported a metal-and-glass dining enclosure, reached by dramatically curving stairways at either end. Completed in four months, it was inaugurated in the presence of government officials and representatives of the company, a degree of ceremony that might seem extravagant for the opening of a highway restaurant today.

Italy was in the midst of the economic transformation subsequently known as the miracolo economico. Industrial production was expanding, household incomes were rising, and automobile ownership was becoming possible for families who had previously depended upon public transportation. The Fiat 500, introduced in 1957, was among the most recognizable expressions of this new prosperity. Meanwhile, construction of the Autostrada del Sole, begun the previous year, promised to connect the industrial north with Rome and Naples through a modern system of high-speed roads.

Mario Pavesi, whose company manufactured biscuits and packaged foods, had recognized the commercial possibilities of automobile travel more than a decade earlier. In 1947, he established a refreshment outlet near the Novara toll station on the Milan–Turin motorway. What began as an opportunity to sell biscuits to passing motorists developed into a business offering coffee, meals, and eventually the range of goods and services associated with the modern motorway service area.

Bianchetti's contribution was to give this commercial arrangement an architectural character commensurate with the ambitions of the new road. At Fiorenzuola, the restaurant was not merely positioned where motorists could see it. It occupied the space above the motorway itself. Seated behind continuous glazing, customers could exchange the position of driver for that of spectator. The traffic became the restaurant's principal attraction.

The building was an advertisement, an engineering accomplishment, a place to eat, and a demonstration of the pleasures of automobile travel. Its appearance depended upon the particular excitement surrounding the motorway, an infrastructure whose novelty was sufficient to make the movement of vehicles an object of interest.

Bianchetti had encountered elevated roadside restaurants during a journey to the United States, and Pavesi had previously drawn inspiration from American grill rooms. Their achievement was not the invention of a building type without precedent, but its adaptation to Italy's rapidly expanding motorway network. The restaurant took an American commercial idea and made it an emblem of Italian modernity.

Throughout the twentieth century, the roadside offered opportunities for architectural invention on a scale that has received relatively little attention outside specialized histories. Gas stations resembled streamlined machinery or oversized consumer products. Motels organized accommodation around the parked automobile. Coffee shops adopted the visual vocabulary of aviation and space travel. Public rest areas introduced modern landscape design into ordinary journeys, while the roads themselves became carefully composed sequences of curves, bridges, planting, and distant views.

The resulting buildings were inconsistent, commercially opportunistic, and sometimes extravagant. They were also among the most direct architectural responses to a fundamental change in everyday experience. The automobile altered not only where people could travel, but the speed at which they encountered the built environment.

The architecture of the roadside emerged from that change.

ARCHITECTURE AT SIXTY MILES AN HOUR

Traditional commercial streets developed around people moving on foot. Shopfronts occupied relatively narrow plots, entrances opened directly onto sidewalks, and signs could be read from distances measured in yards. A pedestrian might approach a building slowly, examine its windows, and decide to enter after considering what was displayed.

The automobile introduced a different relationship between buildings and their audience. A motorist might encounter a restaurant or filling station for only a few seconds before passing it. The opportunity to turn into a driveway could arrive before the driver had finished reading a sign. Buildings needed to communicate across greater distances and under circumstances in which attention was divided between architecture and the demands of operating a vehicle.

These conditions affected the organization of commercial sites. Parking became an essential requirement, and entrances had to accommodate the turning movements of cars. The relationship between the building and the road was no longer necessarily established by a continuous street frontage. A restaurant might stand behind a large forecourt, its façade separated from passing traffic by rows of parked vehicles. The sign could become more prominent than the building itself.

The filling station was among the first commercial types to develop specifically around these conditions. During the early years of motoring, gasoline was frequently sold from pumps outside general stores or other established businesses. As automobile ownership increased, dedicated stations emerged, with pumps, canopies, service bays, offices, and restrooms arranged around the circulation of vehicles.

The customer occupied the site differently from someone entering a conventional shop. Much of the transaction took place outside the building, beside the automobile. Pumps and sheltering canopies were essential architectural components, while the arrangement of the forecourt determined how easily vehicles could arrive, refuel, and leave.

Petroleum companies quickly understood that architecture could contribute to brand recognition. During the 1920s and 1930s, they developed stations in a variety of styles, ranging from buildings resembling modest suburban houses to streamlined structures with rounded corners and broad, cantilevered roofs. The domestic examples offered an appearance of familiarity and respectability; the modern ones associated gasoline with engineering, speed, and mechanical progress.

At the more extravagant end of the spectrum stood the Shell Service Station in Winston-Salem, North Carolina. Constructed in 1930 for a local distributor, the building took the form of an enormous scallop shell. Its curved walls turned the petroleum company's emblem into an architectural object, allowing motorists to recognize the business through the shape of the building itself.

It was an example of what architectural historians would later describe as mimetic or programmatic architecture, in which the form of a building imitates an object associated with its purpose. Restaurants, shops, and roadside attractions adopted the shapes of bottles, teapots, food, and other familiar objects. Their imagery could be absurd, but their commercial logic was unusually direct. A giant shell communicated more quickly than a conventional façade adorned with a modest sign.

The same principle could be expressed through less literal means. Streamlined surfaces, conspicuous rooflines, illuminated signs, and recognizable corporate colors provided motorists with information before they could examine a building closely. Architecture and advertising became increasingly difficult to separate.

These buildings were not simply inferior versions of the commercial structures found in established urban centers. They responded to different circumstances. Their architecture depended upon speed, distance, vehicular circulation, and a competitive environment in which a passing driver might have numerous opportunities to stop.

The roadside became one of the places where modern design entered ordinary commercial life, frequently without the involvement of architects associated with the established cultural institutions of modernism. A filling station or roadside diner could employ forms as adventurous as those of an exhibition pavilion, while serving customers whose principal interests were gasoline, a meal, and a clean restroom.

A ROOM BESIDE THE CAR

The automobile also transformed the architecture of accommodation. Traditional hotels were generally situated near railway stations, ports, commercial districts, or established destinations. Their organization assumed that guests would enter through a common lobby and proceed through shared interior spaces to rooms elsewhere in the building.

Motorists required something less formal. They wanted inexpensive accommodation close to the road, with parking readily available and minimal inconvenience surrounding arrival and departure.

During the early twentieth century, travelers often slept in tents, establishing temporary camps near roads or in spaces provided by municipalities. Towns recognized that automobile tourists could contribute to local commerce, and public camping grounds became one means of encouraging visitors to stop. Some supplied water, toilets, showers, and places to cook. Others offered little more than a level piece of ground.

Private proprietors gradually introduced more substantial accommodation. The automobile camp developed into the cabin court, a collection of small permanent buildings arranged around a shared parking area. A driver could pull almost directly to the entrance of a room, unloading luggage without negotiating the lobby and corridors of a conventional hotel.

During the 1920s and 1930s, cabin courts became familiar features of American highways. Many were independent businesses operated by families who lived on the premises. Their architecture was modest and frequently improvised, but the arrangement was remarkably well suited to automobile travel. Rooms were accessible from outside, parking was immediately available, and the guest retained much of the independence associated with the car.

The Motel Inn in San Luis Obispo, California, opened in 1925, is commonly associated with the emergence of the term motel. Designed by Arthur Heineman, its Spanish Colonial Revival buildings offered an established architectural appearance while accommodating the unfamiliar requirements of the automobile tourist. The novelty lay principally in its organization rather than its decorative vocabulary.

Over time, individual cabins gave way to adjoining rooms beneath continuous roofs, while private bathrooms, heating, restaurants, and swimming pools became increasingly common. The motor court developed into the motel, a building type whose organization placed the parked automobile almost at the guest's door.

The plan represented an extraordinary simplification of hotel circulation. The conventional sequence of entrance, reception, elevator, corridor, and room could be reduced to a parking space and an exterior door. The landscape of the motel was consequently neither fully architectural nor merely vehicular. Its parking court served as the principal space through which guests moved.

Competition encouraged proprietors to establish distinctive identities. Along Route 66 and other important highways, motels adopted regional architectural styles, conspicuous signs, unusual landscaping, and names suggesting comfort or adventure. Some borrowed imagery from distant cultures, while others advertised amenities with the directness of a commercial catalogue.

The Wigwam Village chain, begun during the 1930s, offered one of the most conspicuous examples. Its concrete sleeping units were shaped like tipis, although advertised as wigwams, appropriating Indigenous architectural imagery for commercial novelty. At Holbrook, Arizona, fifteen such units were arranged around a parking area, producing an unmistakable roadside silhouette.

The buildings are historically significant, but their commercial use of Indigenous forms also reveals the cultural assumptions underlying much roadside entertainment. The architecture offered an image of regional distinctiveness without serious concern for the traditions it claimed to evoke.

The motor court gave travelers an unfamiliar degree of independence, but the promise of freedom associated with automobile travel was not distributed equally.

THE FREEDOM TO STOP

For Black Americans traveling during the era of segregation, the ability to own and operate an automobile did not guarantee access to the businesses encountered along the road. Restaurants, hotels, gas stations, and other establishments could refuse service, while unfamiliar communities might expose travelers to harassment or violence. The practical freedom of the automobile therefore depended upon knowledge of where it was possible to stop.

In 1936, Victor Hugo Green, a postal worker from Harlem, began publishing The Negro Motorist Green Book. Initially focused on New York, the guide expanded into a national directory identifying hotels, tourist homes, restaurants, filling stations, and other businesses willing to serve Black travelers. It became an indispensable resource for motorists whose journeys required precautions largely unnecessary for white Americans.

The guide revealed a contradiction within the culture of automobile travel. The car promised independence from railway schedules and greater freedom to choose one's destination, yet the ability to stop for a meal or find accommodation remained subject to racial restrictions. The road was open, but the establishments along it were not.

Black-owned businesses provided an important alternative network of hospitality. Tourist homes, hotels, restaurants, and service stations offered practical services while also sustaining local communities and commercial relationships. Their architectural importance was not always reflected in dramatic buildings or distinctive signage. Often, their significance lay in the ordinary accommodations they made available to people excluded elsewhere.

The history of the Green Book is therefore necessary to any serious account of the American roadside. Architectural accessibility is not simply a matter of entrances, parking spaces, or circulation. It also concerns the people permitted to use a place and the social conditions governing their presence.

The guide continued in publication until 1966, after the Civil Rights Act of 1964 had prohibited discrimination in public accommodations. Its history complicates the customary nostalgia for independent motels and restaurants. Personal ownership and distinctive architecture did not necessarily produce generous hospitality, just as standardized commercial operations were not always devoid of social importance.

The roadside was a place of invention, but also a landscape in which the inequalities of American life were made particularly apparent.

THE RECOGNIZABLE ROAD

As automobile travel expanded, independent roadside businesses increasingly faced competition from companies whose identities extended across regions and eventually the entire country. The architecture of these chains served a different purpose from that of the eccentric individual diner or motel.

Howard Johnson's became one of the most successful examples. The company adopted franchising during the early 1930s, expanding its restaurants along the highways of the Eastern United States. Its characteristic orange roofs made individual establishments recognizable before motorists could read their signs or examine their menus.

The commercial advantage was substantial. A traveler approaching an unfamiliar town could recognize a Howard Johnson's and anticipate a reasonably consistent meal, service, and standard of cleanliness. The roofline was not simply decoration. It communicated a promise about the experience awaiting the customer.

The company opened its first motor lodge in 1954, extending its familiar identity from restaurants to accommodation. By the following decade, the combination of orange roofs, established menus, and recognizable facilities had become an enduring feature of American highway travel.

A related form of architectural recognition developed at Stuckey's. Founded by W. S. Stuckey in Georgia in 1937 as a roadside pecan business, the company expanded into a network of shops selling candy, snacks, souvenirs, and other products associated with automobile tourism.

Its blue-green roofs became distinctive landmarks along highways, supported by a vast system of billboards announcing the approach of the next store. At its height during the 1960s and 1970s, the company operated hundreds of locations across more than thirty states.

Stuckey's offered a different experience from a conventional restaurant. Its shops combined regional food products, travel necessities, inexpensive souvenirs, and the assurance of familiar facilities. The architecture announced not merely the opportunity to purchase something, but a particular kind of interruption in the journey.

The succession of billboards was itself part of the design. A motorist might encounter repeated announcements for many miles before arriving at a recognizable roof. The business therefore occupied a much greater stretch of the roadside landscape than the dimensions of its property suggested. Advertising prepared the traveler to recognize the architecture.

Howard Johnson's and Stuckey's demonstrated that repetition could be as powerful a commercial strategy as novelty. An independent motel might distinguish itself through an unusual form, while a chain benefited from making its establishments resemble one another. Both strategies depended upon recognition, but one promised the unfamiliar and the other the reliably known.

The growing importance of national chains also changed the organization of roadside architecture. Buildings, signs, parking areas, menus, and service practices could be standardized across numerous locations. A site no longer needed a unique architectural identity when its principal commercial value lay in its association with a widely recognized brand.

The result was not necessarily a decline in design quality. It was a different conception of what design should accomplish. Instead of making one establishment distinct from every other, architecture established continuity across an expanding geographical network.

TOMORROW AT THE COFFEE SHOP

In postwar Los Angeles, the commercial competition created by automobile travel produced a more exuberant architectural response. The city's broad streets, extensive road network, and dispersed development encouraged restaurants and coffee shops to address motorists approaching from considerable distances.

Architects experimented with sharply angled roofs, dramatic structural supports, expanses of glass, illuminated signs, and forms associated with aircraft and space technology. The style became known as Googie, after a coffee shop designed by John Lautner on Sunset Boulevard in 1949.

Googie was not a movement organized around a formal manifesto. Its practitioners responded to the conditions of Southern California's commercial environment, where visibility from the automobile was essential and unusual architecture could distinguish an establishment from its competitors.

The partnership of Louis Armet and Eldon Davis, established in 1947, became especially associated with the style. Their restaurants combined dramatic rooflines with practical plans, generous glazing, and conspicuous signage. The architecture was intended to attract attention from the road while providing an inviting environment for customers once they entered.

Johnie's Coffee Shop, completed in 1956 at the intersection of Wilshire Boulevard and Fairfax Avenue, is among the most accomplished surviving examples. Originally called Romeo's Times Square, the building features a dramatically folded roof supported by angled elements and extending above glass walls. Its broad silhouette remains recognizable from several directions, while its illuminated signage reinforces the identity of the establishment.

The roof is the principal event. Its planes rise and project beyond the walls, suggesting movement and mechanical energy. The glazed enclosure beneath allows the interior to remain visually connected to the street, while the structure appears almost disproportionately ambitious for an ordinary coffee shop.

The extravagance was calculated. A modest restaurant became an advertisement for itself, borrowing the visual vocabulary of aviation and engineering to suggest that the activity taking place within belonged to the technological future.

Southern California's aerospace industries and automobile culture provided a receptive environment for such imagery. The excitement surrounding aircraft, rockets, and industrial innovation found expression in domestic appliances, advertisements, restaurants, and commercial buildings. The coffee shop became an accessible setting in which the public could encounter the aesthetics of technological optimism.

Googie architecture was often dismissed as vulgar or excessively commercial, particularly by critics committed to more restrained forms of modernism. Yet the best examples display considerable intelligence in their response to the conditions of the road. Their signs, rooflines, glazing, and parking areas form integrated compositions, rather than arbitrary decorations attached to otherwise conventional buildings.

These restaurants were not designed to be admired solely as isolated architectural objects. They were intended to be noticed from moving cars, approached through parking lots, and occupied by customers whose experience of the building began well before they reached its entrance.

THE ROAD AS LANDSCAPE

The transformation of architecture by the automobile extended beyond the buildings constructed alongside highways. The road itself became a subject of deliberate design, particularly where engineers and landscape architects sought to reconcile the technical requirements of modern transportation with the experience of passing through a landscape.

American parkways provided some of the earliest and most ambitious examples. Unlike ordinary roads intended principally to move traffic efficiently between destinations, parkways were conceived in part as recreational environments. Their alignments, planting, bridges, and views were arranged to make the journey itself a pleasurable experience.

The Blue Ridge Parkway, begun in 1935 as a New Deal public works project, is among the most significant examples. Extending through Virginia and North Carolina, it was designed to connect Shenandoah National Park and Great Smoky Mountains National Park while offering motorists carefully composed views of the Appalachian landscape.

Stanley W. Abbott, the landscape architect who directed much of its early planning, understood the road as a sequence of experiences rather than simply a line connecting distant places. Its route moved between ridges, valleys, forests, and open landscapes, offering changes of scale and perspective intended to sustain the traveler's attention.

Abbott placed particular importance on variety. An uninterrupted succession of spectacular panoramas could become monotonous, he argued, while quieter passages through woods or pastures made the expansive views more rewarding. The design therefore depended upon the controlled alternation of enclosure and openness, intimacy and distance.

The road was an architectural composition experienced through movement. Bridges, retaining walls, planting, and overlooks contributed to the character of the route, while the curvature of the roadway determined how the landscape was progressively revealed.

The overlooks were especially important. They provided opportunities to leave the car, occupy a carefully chosen vantage point, and observe the scenery that had previously passed through the windshield. These spaces were not accidental clearings beside the pavement. They were components of a planned landscape in which the experience of driving and the experience of stopping were closely related.

The project also demonstrates that apparently natural scenery can be the product of extensive design and maintenance. Trees were selectively planted or removed, views were composed, and the relationship between the road and surrounding land was carefully managed. The visitor encountered a landscape presented as picturesque, although the conditions of that encounter had been deliberately constructed.

This tradition differed from the commercial invention of the roadside diner or filling station. The purpose was not to attract customers to a business but to make the road itself a recreational environment. Yet the underlying architectural problem was related: how should a place be designed for people whose principal experience of it occurs through an automobile?

THE PUBLIC REST STOP

The development of the Interstate Highway System introduced another important building type: the publicly provided safety rest area. Its purpose was more modest than that of the private motorway restaurant, but its design raised questions about landscape, public accommodation, and the role of government in the experience of travel.

The Federal-Aid Highway Act of 1956 helped establish a national network of high-speed, limited-access roads. These routes allowed motorists to travel considerable distances without passing directly through towns, but their efficiency also reduced opportunities to stop safely.

Public rest areas provided a response. Located beside the highway and reached through designated exits, they offered parking, restrooms, picnic facilities, and places to walk or recover from the fatigue of driving. Their usefulness depended upon safety and accessibility rather than commercial attraction.

The development built upon earlier roadside parks, which had appeared along American highways during the 1930s. Ohio, for example, opened roadside facilities where motorists could leave the pavement, park beneath trees, and use picnic tables or other basic amenities. The new Interstate system expanded this concept into larger, more systematically planned sites.

Landscape architects and highway departments developed rest areas with separated parking for cars and trucks, paths connecting facilities, planted lawns, shaded picnic spaces, and buildings whose materials often reflected local architectural traditions. A roadside stop could be a comparatively modest composition of shelter, landscape, and circulation, yet its design required careful attention to the movement and comfort of travelers.

Many states used rest areas to express regional identity. Buildings might incorporate local stone, timber, or forms associated with the surrounding landscape. Information boards introduced visitors to nearby destinations, while picnic shelters provided places for families to occupy the roadside without entering a commercial establishment.

The distinction from privately operated facilities was important. An Interstate rest area offered a public service whose value did not depend upon purchasing food, gasoline, or accommodation. Its design was an expression of the responsibilities assumed by government in constructing and maintaining a national transportation network.

There was also a difference in the understanding of stopping. A roadside restaurant encouraged the traveler to become a customer; a public rest area allowed the traveler simply to rest. Its architecture could be modest precisely because it did not have to compete for attention through advertising or conspicuous commercial identity.

The public rest stop belongs in any architectural history of the automobile age because it reveals another possibility for the designed roadside. Not every building encountered during a journey existed to sell something. Some were intended to make the journey safer, more comfortable, or more rewarding in itself.

THE ITALIAN MOTORWAY

In Italy, the roadside took on a particularly ambitious architectural character during the economic expansion of the 1950s and 1960s. Automobile ownership increased rapidly, the motorway network grew, and food manufacturers recognized the opportunity to associate their products with the pleasures of modern travel.

Mario Pavesi's motorway businesses were soon joined by competitors including Motta and Alemagna. Each company developed service areas where travelers could purchase food and refreshments, and the architecture of these establishments became an important means of commercial distinction.

Angelo Bianchetti was central to the development of the most spectacular examples. Born in 1911, he studied architecture at the Polytechnic University of Milan and began working with Pavesi in 1949. His designs combined modern engineering with an unusually direct understanding of the promotional role buildings could perform.

In 1958, Bianchetti designed Villoresi Ovest on the Milano–Laghi motorway near Lainate. The restaurant occupied a circular glass-walled pavilion beneath three enormous white arches, whose structure supported the Pavesi emblem fifty-one meters above the ground.

The scale was extraordinary for an establishment devoted to refreshments. From the road, the arches resembled an experimental launch structure or a pavilion prepared for an international exposition. Their purpose was partly promotional, making the service area recognizable from a considerable distance, but their appearance also expressed a fascination with engineering and the technological future.

Villoresi became an emblem of Italian modernization. Its architecture was sufficiently remarkable to attract international attention, appearing in Life magazine in September 1960 as part of a broader account of Europe's postwar recovery. The building made an ordinary commercial activity appear inseparable from the country's industrial ambitions.

The following year, Bianchetti completed the bridge restaurant at Fiorenzuola. Where Villoresi established a landmark beside the motorway, Fiorenzuola placed the dining room above it. Customers could reach the restaurant from service areas on opposite sides and watch the traffic moving beneath the structure.

The concept had American precedents, but its Italian expression was unusually confident. Reinforced concrete, metal, and glass were organized into a composition in which architecture and advertising were closely integrated. The great Pavesi lettering announced the establishment, while the building's position over the motorway made it an unmistakable part of the transportation system.

The response from competitors was swift. In 1961, Motta opened its bridge restaurant at Cantagallo, near Bologna, designed by Melchiorre Bega. Its facilities were unusually extensive, incorporating shopping and personal services alongside food and refreshments. The motorway restaurant was becoming a commercial destination whose attractions extended beyond the immediate needs of travelers.

During the following decade, more than a dozen bridge-style restaurants were constructed in Italy. Their popularity reflected a moment when the automobile and the modern motorway were still associated with new possibilities for leisure and consumption.

Families sometimes visited the bridge restaurants for Sunday lunch, watching passing vehicles through the windows before purchasing products advertised on television. The establishments brought together several defining features of the economic boom: private mobility, industrial food production, modern architecture, and expanding consumer choice.

The Italian motorway restaurant did not simply imitate American roadside design. It adapted forms encountered abroad to the conditions of a country undergoing rapid industrial and social change. Its monumental scale and conspicuous engineering expressed a belief that the infrastructure of everyday life could become an object of architectural celebration.

THE AMERICAN OASIS

The development of elevated motorway restaurants was not confined to Europe. In the United States, bridge-style facilities appeared on toll roads during the 1950s, including the Will Rogers Turnpike in Oklahoma and the Illinois Tollway system around Chicago.

The Illinois examples are particularly instructive because they developed at almost the same moment as Bianchetti's Italian experiments. Five original tollway oases were constructed in 1959, their restaurants positioned above the roadway and accessible from parking and service areas on either side.

The arrangement offered several practical advantages. A single restaurant could serve traffic traveling in both directions, while motorists could stop without leaving the controlled-access tollway system. The elevated dining rooms provided panoramic views of the vehicles below, making the highway itself part of the experience.

The original Illinois facilities combined Standard Oil service stations with restaurants operated by the Fred Harvey company. Their construction was financed through commercial arrangements associated with the tollway, demonstrating how private enterprise and public infrastructure could be brought together in a single development.

The Fred Harvey name carried its own history of transportation hospitality. During the late nineteenth and early twentieth centuries, Harvey House restaurants had become familiar features of American railway travel, establishing standards of food and service along routes where adequate accommodation was often scarce. The tollway oases represented an adaptation of that commercial tradition to the age of the automobile.

The bridge restaurant therefore belonged to a longer history of businesses organized around transportation systems. Railway dining rooms, station hotels, motorway restaurants, and airport concessions all responded to the practical needs of people traveling through environments whose primary function was movement.

The Illinois oases were also recreational attractions. Their elevated dining rooms offered views of the tollways, and families sometimes visited simply to watch the traffic pass beneath them. The arrangement resembled the Italian experience closely enough to complicate any simple distinction between an adventurous European roadside and a more commercially standardized American one.

What differed was the institutional setting. The Illinois oases were developed through the relationship between a state tollway authority, petroleum companies, and restaurant operators. Their purpose was to provide services within a new transportation network, with the architecture offering a conspicuous and practical expression of that arrangement.

The later history of the oases reveals how changing requirements could alter the value of the original design. During the 1970s, Howard Johnson's replaced the Fred Harvey restaurants, and fast-food chains subsequently occupied many of the facilities. Extensive reconstruction during the early 2000s replaced much of the original architecture with contemporary glass-and-steel structures.

Some oases were eventually demolished to accommodate highway widening and changes in traffic circulation. The Des Plaines Oasis, once a familiar landmark on the Northwest Tollway, closed in 2014 as part of major transportation improvements. Its removal demonstrated the vulnerability of a building whose unusual position had initially made it so attractive. The same relationship to the road that gave the restaurant its architectural identity eventually placed it in the path of further infrastructure development.

The Illinois oases provide a useful counterpoint to the Italian motorway restaurants. Both were products of new controlled-access roads and the desire to make travel more comfortable and appealing. Both turned the movement of cars into a visual attraction. Their similarities reveal that the automobile produced related architectural experiments across national boundaries, even when the commercial and institutional circumstances differed.

LEARNING FROM THE ROAD

In 1968, Robert Venturi, Denise Scott Brown, and a group of Yale students undertook a study of the Las Vegas Strip. Their subject was an environment that much of the architectural profession had dismissed as vulgar: a landscape of casinos, enormous signs, parking lots, commercial buildings, and broad roads.

The research became the basis of Learning from Las Vegas, published in 1972 with Steven Izenour as a coauthor. The book challenged architectural conventions that valued formal originality and monumental composition while neglecting the ordinary commercial environments in which much of modern life took place.

Las Vegas was an especially useful subject because its buildings were organized around the perception of motorists. Signs communicated identity from considerable distances, parking lots separated commercial structures from the road, and architectural forms competed for attention through scale, color, and illumination.

Venturi, Scott Brown, and Izenour argued that architecture could communicate through symbolism and applied information as well as through its physical form. Their distinction between the duck and the decorated shed provided a vocabulary for understanding buildings that represented their purposes through their overall shape and those that relied upon signs to communicate commercial meaning.

The giant Shell filling station was an obvious example of a building whose form became its message. A modest motel with an enormous neon sign followed a different principle, separating the practical enclosure from the means by which it addressed passing motorists.

Bianchetti's Italian service areas were more complicated. Their striking forms were advertisements, but also responses to the requirements of motorway construction and travel. The bridge restaurant was not merely a symbol attached to a conventional building; its structure made possible the particular experience being sold.

The achievement of Learning from Las Vegas was not to propose that every commercial building deserved admiration. It was to insist that these environments deserved examination. Architectural criticism could learn from the ways buildings communicated, from the practical needs of their users, and from the economic forces responsible for their construction.

A related investigation was undertaken by the artist Ed Ruscha. In 1966, he published Every Building on the Sunset Strip, an accordion-fold book composed of photographs showing both sides of a section of Sunset Boulevard in Los Angeles. The images were made from a moving vehicle and assembled into continuous panoramas, presenting the streetscape as a succession of ordinary buildings rather than a collection of individual architectural monuments.

Ruscha's project offered a different way of seeing the roadside. Buildings appeared alongside one another, their signs, façades, and commercial identities forming a continuous environment. The photographs did not distinguish between architecturally important structures and ordinary businesses. Their subject was the street as encountered through movement.

The artist's method also revealed something about the relationship between the automobile and architectural perception. The building was no longer necessarily an isolated object approached from a privileged viewpoint. It became one element in a sequence, understood through changing positions, distances, and the speed of the observer.

Together, Ruscha's project and Learning from Las Vegas helped establish the commercial roadside as a legitimate subject of cultural and architectural study. What had often appeared to be an incoherent accumulation of signs and buildings could be examined as an environment with its own conventions and forms of intelligence.

THE ROAD THAT PASSED THEM BY

The architectural inventiveness of the roadside depended upon commercial and geographical conditions that were themselves subject to rapid change. As roads were improved, widened, or replaced, the relationship between buildings and their customers could be transformed.

In the United States, the development of the Interstate Highway System after the Federal-Aid Highway Act of 1956 altered long-distance travel. New limited-access routes frequently bypassed the towns and commercial roads that had sustained independent motels, diners, and service stations.

A building designed to attract passing traffic could find itself stranded when motorists began traveling along a new highway several miles away. Its roofline remained conspicuous, its signs still illuminated the road, but the principal audience for which it had been designed had disappeared.

The Blue Swallow Motel in Tucumcari, New Mexico, illustrates the consequences. Opened in 1942 along Route 66, the motel consisted of fourteen units arranged in an L-shaped plan, with garages positioned between guest rooms. Its modest Southwestern architectural details and prominent neon sign gave the establishment a distinctive identity, while its arrangement allowed travelers to park immediately beside their accommodation.

During the 1950s, Lillian Redman and her husband acquired the property. Redman became known for her unusually personal approach to hospitality, sometimes accommodating guests who could not afford a room. The motel's identity developed through her relationship with travelers as much as through its buildings or signage.

The completion of Interstate 40 around the end of the 1960s diverted much of the traffic that had sustained businesses along Route 66. The effect on Tucumcari was considerable. Motels and restaurants that had depended upon passing motorists now confronted a transportation landscape organized around a different road.

Redman continued to operate the Blue Swallow, and the property eventually acquired recognition as a historic landmark. It was listed on the National Register of Historic Places in 1993 and remains in operation, its architecture preserving the intimate relationship between car, parking space, and guest room characteristic of the earlier motor court.

Its continued existence demonstrates that roadside preservation involves more than conserving unusual buildings. The motel's historical significance also lies in the habits, commercial practices, and personal relationships that developed within its particular arrangement of rooms and parking spaces.

In Italy, the problem of preservation has taken a different form. Bianchetti's Villoresi Ovest survived for decades as a recognizable motorway landmark, but changing commercial requirements eventually prompted a substantial reconstruction. When the service area reopened in 2020, its famous three arches remained, while the restaurant building beneath them had been replaced.

The decision preserved the most conspicuous feature of the original design but altered the architectural relationship between structure, enclosure, and commercial activity. The arches survived as an emblem of the economic boom, even as the facilities they had once identified were reorganized for contemporary use.

The Illinois tollway oases faced comparable pressures. Their elevated positions made them distinctive, but also complicated road widening and changing traffic requirements. Several have been rebuilt or demolished, leaving a diminished record of an architectural experiment that was once central to the identity of the tollway system.

Such changes are not simply evidence of cultural neglect. Roadside buildings are commercial and infrastructural objects, and their continued use depends upon changing conditions of travel. A structure designed to serve the requirements of one era may be difficult to reconcile with the demands of another.

Nevertheless, their disappearance presents a historical loss. The motel, the gas station, the coffee shop, the public rest stop, and the bridge restaurant were among the characteristic building types of the automobile age. Their forms record changes in transportation, business, leisure, and the organization of everyday life.

The value of these buildings is not confined to the distinction of their architects. Many were produced by anonymous designers, corporate planning departments, or independent proprietors responding to immediate commercial needs. Their significance emerges from the relationship between their physical forms and the particular circumstances that brought them into existence.

Some are remarkable because they are exceptional. Others matter because they were once ordinary.

THE ROAD AS A DESTINATION

The architecture of the roadside did not develop according to a single national style or coherent theory. It emerged from a succession of practical problems: how to attract the attention of motorists, where to park their cars, how to provide food and accommodation, how to make a journey more comfortable, and how to organize large numbers of people moving through unfamiliar landscapes.

Its buildings answered these problems in different ways. The American motor court reduced the distance between a vehicle and a guest room. The chain restaurant made a particular roofline into a promise of familiar service. The Googie coffee shop employed dramatic forms to communicate across a broad commercial street. The Blue Ridge Parkway treated the experience of movement as a designed landscape, while the public Interstate rest area provided a place to stop without requiring a purchase.

The Italian motorway restaurant brought several of these ambitions together. It combined commercial service, modern engineering, corporate advertising, and an architectural celebration of automobile travel. The bridge restaurant made the motorway itself part of the experience, allowing the flow of traffic to become a spectacle observed from above.

The Illinois oases demonstrate that this architectural idea belonged to a wider history of transportation infrastructure, one in which public agencies and private businesses experimented with forms that could serve travelers moving through new networks of roads.

These buildings were often designed with little expectation of permanence. Restaurants were altered, filling stations replaced, motels adapted, and roads reconstructed. Their architecture belonged to a commercial world in which change was frequently a condition of survival.

Yet their most accomplished examples retain a particular fascination. They express an unusually direct relationship between architecture and the circumstances in which people encounter it. The roadside building does not wait for the observer to approach on foot. It announces itself across the landscape, responds to the movement of vehicles, and provides a reason to interrupt a journey.

At Fiorenzuola, Bianchetti took that relationship to its logical conclusion. He placed the restaurant above the motorway, turning passing traffic into the view from the dining room. Drivers who had spent the morning watching the landscape through their windshields could sit beside a window and watch other motorists continue beneath them.

The road, which ordinarily disappeared behind the moving car, became something to observe. Bianchetti built a restaurant for the purpose.
