Park Avenue Viaduct

The 42nd Street Airlines Terminal, on the southwest corner of Park Avenue and 42nd Street in Midtown Manhattan, was the first of three airline terminals constructed in New York City. It was located at the site of the former Hotel Belmont. During this period of aviation, reservations, ticketing and baggage handling took place at this facility for the airlines American, Eastern, TWA, United and Pan Am. Passengers would be transferred by bus to Newark Airport, and later to the New York International Airport. The changing economics and increasing popularity of air travel eventually led to the creation of new air terminals: the East Side Airline Terminal near the Queens Midtown Tunnel and the West Side Airline Terminal near the Lincoln Tunnel. In 1954 this facility, which had become restricted to ticketing only, was renamed the Airlines Building. The declining importance of the facility led to its demolition in 1978, to become the site of the Philip Morris Building at 120 Park Avenue.

Pershing Square is a public plaza in Manhattan, New York City, located where Park Avenue and 42nd Street intersect in front of Grand Central Terminal. The main roadway of Park Avenue crosses over 42nd Street on the Park Avenue Viaduct, also known as the Pershing Square Viaduct. Two service roads, one northbound and one southbound, connect 42nd Street with the main roadway of Park Avenue, at 40th Street. Pershing Square was named after John J. Pershing in 1919. The name was originally supposed to apply to the block bounded by Park Avenue, Lexington Avenue, 41st Street, and 42nd Street. Three buildings were ultimately developed on the block in the 1920s: the Pershing Square Building, 110 East 42nd Street, and the Chanin Building. Subsequently, the name applied to the service roads of the Park Avenue Viaduct. A tourist information center under the viaduct, at Pershing Square, was built in 1939; it was later reconfigured to be a store and then a restaurant. The service roads between 42nd and 41st Streets were converted into a pedestrian public plaza in 2018.

The Pershing Square Building, also known as 125 Park Avenue or 100 East 42nd Street, is a 25-story office building in Midtown Manhattan in New York City. It is located on the eastern side of Park Avenue between 41st and 42nd streets, across from Grand Central Terminal to the north and adjacent to 110 East 42nd Street to the east. The Pershing Square Building was designed in the Romanesque Revival style by John Sloan and T. Markoe Robertson of the firm Sloan & Robertson, working with York and Sawyer. It was erected within "Terminal City", a collection of buildings located above the underground tracks surrounding Grand Central, and makes use of real-estate air rights above the tracks. The building is located directly above the New York City Subway's Grand Central–42nd Street station. The Pershing Square Building, as well as 110 East 42nd Street, were built on the site of the Grand Union Hotel. Construction started in 1921 and was completed in 1923. Ownership of the Pershing Square Building passed to several companies; the latest such change occurred in 2010, when SL Green Realty bought the building. It was made a New York City designated landmark in 2016.

The Grand Central–42nd Street station (also signed as 42nd Street–Grand Central) is a major station complex of the New York City Subway. Located in Midtown Manhattan at 42nd Street between Madison and Lexington Avenues, it serves trains on the IRT Lexington Avenue Line, the IRT Flushing Line and the 42nd Street Shuttle. The complex is served by the 4, 6, and 7 trains at all times; the 5 and 42nd Street Shuttle (S) trains at all times except late nights; the <6> train during weekdays in the peak direction; and the <7> train during rush hours and early evenings in the peak direction. The station is adjacent to Grand Central Terminal, which serves all Metro-North Railroad lines east of the Hudson River. There are multiple exits to Grand Central Terminal and to nearby buildings such as One Vanderbilt and the Chrysler Building. Numerous elevators make the station compliant with the Americans with Disabilities Act of 1990. The present shuttle station was constructed for the Interborough Rapid Transit Company (IRT) as an express station on the city's first subway line, which was approved in 1900. The station opened on October 27, 1904, as one of the original 28 stations of the New York City Subway. As part of the Dual Contracts, the Flushing Line platform opened in 1915. After the Lexington Avenue Line platforms opened in 1918, the original station became the eastern terminal of the 42nd Street Shuttle, reconfigured with three tracks and two platforms. The Grand Central–42nd Street station complex has been reconstructed numerous times over the years, including in the early 21st century, when the shuttle station was reconfigured. Grand Central–42nd Street is the second busiest station in the 424-station system, with 45,745,700 passengers in 2019; only the Times Square station complex has more riders.

The Grand Central station was the terminal for some trains of the IRT Third Avenue Line, also known as the Third Avenue El, in Manhattan, New York City. This station originally had one island platform and two side platforms, all connected at the west end (later converted to three tracks and two island platforms). The tracks ended just east of the Park Avenue Viaduct ramp over Pershing Square.It opened August 26, 1878, and served not only Grand Central Terminal but also its two predecessors, Grand Central Station (1899-1913) and Grand Central Depot (1871-1899). When the El opened north of 42nd Street in September 1878, this segment was reduced to a shuttle, which connected to the mainline at the 42nd Street station, at Third Avenue. In 1904, the Interborough Rapid Transit Company opened the Grand Central station as part of the its first subway line. Platforms for the IRT Flushing Line opened in 1915, followed by those for the IRT Lexington Avenue Line in 1918; after the Lexington Avenue Line platforms opened, the original platforms at the station were converted for use by the 42nd Street Shuttle. By this time, the El station had become obsolete and it was closed on December 6, 1923.

Grand Central Tower (also known as 175 Park Avenue) was a scrapped proposal by Penn Central to have a skyscraper built on top of Grand Central Terminal in 1968. It was designed by Marcel Breuer and would have been 950 feet (290 m) tall. The plan itself drew major opposition from the public and architects, especially from Jacqueline Kennedy Onassis, as it would have resulted in the destruction of the terminal. The plan was scrapped after it was settled in a court case in 1978, which meant Penn Central could not build the tower.
