Park Avenue is a boulevard in New York City[5] that carries north and southbound traffic in the boroughs of Manhattan and the Bronx.

Later on, the railroad was run through an open cut tunnel under Murray Hill, which was then covered with grates and grass between 34th and 40th Street in the early 1850s.

[10] As part of the project, Fourth Avenue was transformed into a boulevard with a median strip that covered the railroad's ventilation grates.

[18][19] The New York state legislature subsequently passed a law to ban all steam trains in Manhattan.

[22] After the electric trains were buried underground, the area around Park Avenue in the vicinity of Grand Central was developed into several blocks worth of prime real estate called Terminal City.

Stretching from 42nd to 51st Streets between Madison and Lexington Avenues, it came to include the Chrysler Building and other prestigious office buildings; luxury apartment houses along Park Avenue; and an array of high-end hotels that included the Marguery, Park Lane, and Waldorf Astoria.

To ensure his corporate name was accurate, Mandel asked the New York City Board of Aldermen to move Park Avenue's southern terminus to 32nd Street.

[28] The Board of Aldermen summarily overturned the name change,[9] but Mayor John Hylan vetoed the move in April 1925.

[29] This prompted Bacon to appeal the decision to the New York Supreme Court, Appellate Division, which overturned Hylan's veto in November 1927, on the basis that the extension of Park Avenue to 32nd Street had been made for the benefit of a developer.

[31][32] Bacon contemplated bringing up the matter with the United States Supreme Court,[33] but she ultimately relented, changing her address to "Park Avenue at 34th" by 1930.

In 1927, the medians on Park Avenue north of Grand Central were trimmed to add one lane of traffic in each direction.

[34] In the 1920s the portion of Park Avenue from Grand Central to 96th Street saw extensive apartment building construction.

[36] A tradition was introduced in 1945 as a memorial to American soldiers killed in action, whereby Christmas trees are placed in the median and lit up on the first Sunday in December at Brick Presbyterian Church.

In 1997, the NYCDOT commissioner stated that signals would be installed during an upcoming phase of reconstruction in the Grand Central area.

Because the roof was 18 to 24 inches (46 to 61 cm) thick, there was not enough room to provide a foundation for the traffic poles without puncturing the structure.

Due to the high cost of making these upgrades, and the lack of cooperation between the New York City Department of Transportation and Metro-North, which had opposed any solution that would modify the tunnel roof, the project was delayed for several years.

[46] In 2019, the Metropolitan Transportation Authority provided funding for repairs to the roof of the Grand Central Terminal train shed.

[48] In August 2024, the city government began soliciting bids for the reconstruction of Park Avenue's median between 46th and 57th Streets.

Park Avenue in Manhattan ends north of 132nd Street, with connections to the Harlem River Drive.

The begonia was specifically chosen by the Fund's gardeners because there is no automatic watering system and the floral variety is resilient under hot sun rays.
