Park Avenue (Manhattan)

Park Avenue is a wide New York City boulevard which carries north and southbound traffic in the borough of Manhattan. For most of the road's length in Manhattan, it runs parallel to Madison Avenue to the west and Lexington Avenue to the east. Park Avenue's entire length was formerly called Fourth Avenue; the title still applies to the section between the Bowery and 14th Street. The avenue is called Union Square East between 14th and 17th Streets, and Park Avenue South between 17th and 32nd Streets.

Early years and railroad construction
Park Avenue was originally known as Fourth Avenue and carried the tracks of the New York and Harlem Railroad starting in the 1830s. The railroad originally ran through an open cut through Murray Hill, which was covered with grates and grass between 34th and 40th Street in the early 1850s. A section of this "park" was later renamed Park Avenue in 1860, and the name was later applied to the segment between Union Square and 42nd Street.

The Harlem Railroad was later incorporated into the New York Central Railroad, and a terminal for the New York Central at 42nd Street, the Grand Central Depot, opened in 1871. But the tracks laid to the new terminal proved problematic. There were originally no grade-separated crossings of the railroads between 42nd and 59th Streets. As such, they required railroad crossings along Fourth Avenue, which resulted in frequent accidents; seven people died within 12 days of the Hudson River Railroad's move to Grand Central.

In 1872, shortly after the opening of Grand Central Depot, New York Central owner Cornelius Vanderbilt proposed the Fourth Avenue Improvement Project. The tracks between 48th and 56th Streets were to be moved into a shallow open cut, while the segment between 56th and 97th Streets, which was in a rock cut, would be covered over. After the improvements were completed in 1874, the railroads, approaching Grand Central Depot from the north, descended into the Park Avenue Tunnel at 96th Street and continued underground into the new depot. As part of the project, Fourth Avenue was transformed into a boulevard with a median strip that covered the railroad's ventilation grates. Eight footbridges crossed the tracks between 45th and 56th Streets, and there were also vehicular overpasses at 45th and 48th Streets. The boulevard north of Grand Central was renamed Park Avenue in 1888.

Grand Central and Terminal City
A fatal collision between two trains occurred under Park Avenue in 1902, in part because the smoke coming from the steam trains obscured the signals. The New York state legislature subsequently passed a law to ban all steam trains in Manhattan. By December 1902, as part of an agreement with the city, New York Central agreed to put the approach to Grand Central Station from 46th to 59th Streets in an open cut under Park Avenue, and to upgrade the tracks to accommodate electric trains. Overpasses would be built across the open cut at most of the cross-streets. The new electric-train terminal, Grand Central Terminal, was opened in 1913.

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. In 1929, New York Central built its headquarters in a 34-story building (now called the Helmsley Building), straddling Park Avenue north of the terminal.

The Park Avenue Viaduct reroutes Park Avenue around Grand Central Terminal between 40th and 46th Streets, allowing Park Avenue traffic to traverse around the building and over 42nd Street without encumbering nearby streets. The western (now southbound) leg of the viaduct was completed in 1919, but congestion developed soon after the viaduct's opening, so an eastern leg for northbound traffic was added in 1928.

Later years
In 1927, the medians on Park Avenue north of Grand Central were trimmed to add one lane of traffic in each direction. This project eliminated the pedestrian path on the medians, as they became much narrower. The median was extended by one block from 96th Street to 97th Street in 1941, creating the only remaining median on Park Avenue with a pedestrian path and seating. In the 1920s the portion of Park Avenue from Grand Central to 96th Street saw extensive apartment building construction. This long stretch of the avenue contains some of the most expensive real estate in the world. Real estate at 740 Park Avenue, for example, sells for several thousand dollars per square foot.

In October 1937, a part of the Murray Hill Tunnel was reopened for road traffic. Efforts to promote a Grand Park Avenue Expressway to Grand Concourse in the Bronx were unsuccessful.

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. On May 5, 1959, the New York City Council voted 20–1 to change the name of Fourth Avenue between 17th and 32nd Streets to Park Avenue South. The renaming, along with a ban on overhanging signs along the newly renamed Park Avenue South, was intended to improve the character of the avenue. The Pan Am Building (now MetLife Building), in between the Park Avenue Viaduct's legs north of Grand Central Terminal, was opened in 1963.

On March 12, 2014, two apartment buildings near 116th Street, 1644 and 1646 Park Avenue, were destroyed in a gas explosion. Eight people were killed and many others were injured.

Manhattan
The road that becomes Park Avenue originates at the Bowery. From Cooper Square at 8th Street to Union Square at 14th Street, it is known as Fourth Avenue, a 70 foot road carrying northbound traffic. At 14th Street, it turns slightly northeast to align with other avenues drawn up in the Commissioners' Plan of 1811. From 14th Street to 17th Street, it forms the eastern boundary of Union Square and is known as Union Square East; its southbound lanes merge with Broadway south of 15th Street, and the thoroughfare divides into two distinct portions in the one-block section between 14th and 15th Streets. From 17th Street to 32nd Street, it is known as Park Avenue South. Above 32nd Street, for the remainder of its distance, it is known as Park Avenue, a 140-foot-wide boulevard.

Between 33rd Street and 40th Street, the left-hand northbound lane descends into the Murray Hill Tunnel. Immediately across from 40th Street, the center lanes of Park Avenue rise onto an elevated structure that goes around Grand Central Terminal and the MetLife Building (formerly the PanAm Building), carrying each direction of traffic on opposite sides of the buildings. The bridge, one of two structures in Manhattan known as the Park Avenue Viaduct, returns to ground level at 46th Street after going through the Helmsley Building (also referred to as the New York Central Building or 230 Park Avenue). The IRT Lexington Avenue Line runs under this portion of the street. Once the line reaches Grand Central–42nd Street, it shifts east to Lexington Avenue.

As Park Avenue enters Midtown north of Grand Central Terminal, it is distinguished by many glass-box skyscrapers that serve as headquarters for corporations and investment banks such as Société Générale, JPMorgan Chase at 270 Park Avenue and 277 Park Avenue, UBS at 299 Park Avenue, Citigroup, Colgate-Palmolive, and MetLife at the MetLife Building. Prior to July 2010, the eleven intersections between 46th Street and 56th Street lacked the city's usual pedestrian crossing signals and overhead gantry-mounted traffic lights, because the railroad tunnel ceiling, which is also the street, was not thick enough for their poles' foundations. (These intersections did, however, have upright pole-mounted traffic lights prior to 2010, but there were no pedestrian signals. After 2010, standard gantry-mounted traffic lights and pedestrian "countdown" signals were installed.)

From 47th to 97th Streets, the tracks for Metro-North Railroad's Park Avenue main line run in the Park Avenue Tunnel underneath Park Avenue. At 97th Street, the tracks come above ground, rising onto the other Manhattan structure known as the Park Avenue Viaduct. The first street to pass under the viaduct is 102nd Street; from there to the Harlem River the railroad viaduct runs down the middle of Park Avenue. Park Avenue in Manhattan ends north of 132nd Street, with connections to the Harlem River Drive.

The flowers and greenery in the median of Manhattan's Park Avenue are privately maintained, by the Fund for Park Avenue. 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.

The Bronx
The avenue is continued on the other side of the river in the Bronx. In the Bronx, Park Avenue begins at East 135th Street in the Mott Haven neighborhood. The entire avenue is divided by Metro-North's own right of way in the borough. Between East 135th Street to East 173rd Street, Park Avenue is one way only in either direction in most sections. North of East 173rd Street it is a two way avenue continuing to Fordham Plaza where it ends.
