Park Avenue Viaduct: The Evolution of a Manhattan Landmark
The space beneath the Park Avenue viaduct, nestled between 41st and 42nd streets, has served as a mirror to New York City's changing urban needs. From its industrial beginnings as a trolley barn to its current state as a modern pedestrian sanctuary, this unique architectural void has transitioned through various roles, reflecting the city's shift from transit-centric infrastructure to pedestrian-focused public spaces.
The Early Years: Information and Service
In preparation for the 1939 New York World's Fair, the city reimagined the viaduct's undercroft. A steel and glass-brick structure was erected under the center arch at 90 East 42nd Street, opening in December 1939 as a tourist information center. This space proved versatile over the following decades; during World War II, it served the United Service Organizations (USO), and in the post-war era, it functioned as an outpost for the New York Convention and Visitors Bureau. By the 1980s, the building's utility had shifted again, serving as an unemployment office.

By 1987, the Grand Central Partnership began envisioning a more vibrant use for the area, proposing the closure of the lightly used western leg of Pershing Square. By 1989, the goal evolved: the space under the viaduct—then occupied by the discount retailer North Pole Stores—was slated to become a restaurant, and the section of Pershing Square between 41st and 42nd streets was to be closed to traffic.
The path to conversion was not without obstacles. Manhattan Community Board 5 opposed the closure of the Park Avenue block, noting that it was the only point between Second and Seventh Avenues where eastbound traffic on 42nd Street could turn right. Additionally, the city required the project to undergo the Uniform Land Use Review Procedure (ULURP), a lengthy zoning process. Despite these hurdles, the area's popularity grew; by mid-1995, the section of Park Avenue between 41st and 42nd streets was closed every weekday from 11 a.m. to 3 p.m., becoming a popular lunch spot for local office workers.
The Birth of Pershing Square Cafe
In November 1995, a $2 million restoration plan was unveiled. The Pershing Square Cafe signed its lease in 1997, but the operator, Michael O'Keeffe, pursued a meticulous renovation that drove costs up to $5 million and delayed the opening. The cafe's design featured authentic historical details, including slot-headed screws consistent with the original viaduct construction, hand-rubbed paint, and chairs and electric cords imported from Paris. The layout placed the entrance on 42nd Street and the kitchen near 41st Street.

The most recent chapter of the viaduct's history focuses on pedestrianization. In 2009, Manhattan Community Board 5 recommended converting the service roads into a public pedestrian plaza. This vision began to materialize in 2013 when the New York City Department of Design and Construction (DDC) announced a $2 million project to permanently close the southbound western roadway.
Designed by Quennell Rothschild & Partners, the western plaza—featuring terraces, a rain garden, and asphalt-and-concrete blocks—opened in May 2019 after construction began in 2018. The transformation continued with the eastern roadway, which began its conversion in December 2021. This final phase, costing $16.7 million, culminated in the opening of the eastern plaza at the end of May 2025.
