The FDR Drive (officially referred to as the Franklin D. Roosevelt East River Drive) is a 9.68-mile (15.58 km) limited-access parkway on the east side of the New York City borough of Manhattan. It starts near South and Broad Streets, just north of the Battery Park Underpass, and runs north along the East River to the 125th Street / Robert F. Kennedy Bridge / Willis Avenue Bridge interchange, where it becomes the Harlem River Drive. All of the FDR Drive is designated New York State Route 907L (NY 907L), an unsigned reference route. The FDR Drive features a mix of below-grade, at-grade, and elevated sections, as well as three partially covered tunnels. The parkway is mostly three lanes in each direction, with the exception of several small sections.
By law, the current weight limits on the FDR Drive from 23rd Street to the Harlem River Drive in both directions is posted 8,000 pounds (3,600 ;kg). Buses are not allowed to use the roadway north of 23rd Street because they exceed the road’s maximum clearance and weight. All commercial vehicles (including trucks) are banned from all sections of the FDR Drive, except for a short section just north of the Battery Park Underpass where the northbound lanes temporarily merge with South Street. The East River Greenway runs below, beside, or above the FDR Drive along nearly its entire length, except for a section between 38th and 60th Streets. A plaque dedicating the East River Drive is visible on the southbound roadway before entering the Gracie Mansion tunnel at 90th Street.
FDR Drive starts at the southern tip of Manhattan at South and Whitehall Streets in the Financial District. It rises from the underground Battery Park Underpass to an elevated viaduct above South Street, with an at-grade connection to South Street at exit 1. The elevated viaduct continues northeast, with an interchange at Brooklyn Bridge at exit 2. The elevated road, also known as the South Street Viaduct, continues until Gouverneur Slip, near the Manhattan Bridge interchange (exit 3), where there is a southbound exit and northbound entrance. From here, the road is at-grade, with a southbound exit/entrance at Grand Street, exit 4. The FDR Drive continues north through Lower East Side and Alphabet City, and dips under Houston Street at exit 5, in a three-way interchange. It continues north as an at-grade road. Between 14th and 15th Streets, the FDR Drive passes a large Con Edison substation. The substation is surrounded by ramps for the former exit 6, a southbound exit and entrance which was closed after September 11, 2001. By 18th Street, the FDR Drive curves north onto an elevated viaduct above Avenue C. The elevated viaduct continues until 25th Street in order to serve the 23rd Street interchange at exit 7. This exit serves the neighborhood of Kips Bay. At 23rd Street, Avenue C continues as the northbound service road for the FDR Drive, while the southbound lanes split from the main highway at 25th Street.
The FDR Drive continues north as an at-grade road, with the Waterside Plaza complex located along the East River to the east of the parkway. The southbound lanes ascend to a viaduct at 28th Street, and the southbound lanes ascend at 30th Street. There is a southbound entrance and northbound exit at ground level at 28th-30th Streets, where the southbound service road begins again. The northbound exit, labeled exit 8, serves 34th Street in Murray Hill, which is located four blocks north; the FDR Drive service road curves underneath the main highway until 36th Street. Another southbound entrance is located at 34th Street itself, and rises to the viaduct level. At 38th Street, the northbound-only exit 9 for 42nd Street, serving Turtle Bay, splits from FDR Drive. Exit 9 continues as an elevated ramp until the intersection of 42nd Street and First Avenue, where it becomes the westbound lanes of 42nd Street. The FDR Drive dips onto street level and merges with the northbound service road. The southbound service road continues parallel to the FDR Drive, and the southbound exit 8 splits from the parkway near 41st Street. The southbound service road then becomes the eastbound lanes of 42nd Street. The headquarters of the United Nations was constructed on a platform above the at-grade FDR Drive from 42nd to 48th Streets. The southbound roadway is inside a later structure resembling a tunnel while the northbound roadway is located just outside of the tunnel. This section is often referred to as the United Nations Tunnel, even though only the westernmost lane of the northbound roadway is under the structure. At 48th Street, the FDR Drive emerges from the United Nations tunnel. A northbound ramp from First Avenue merges onto the northbound roadway. The southbound roadway contains two exits: exit 10 at 49th Street, and exit 11 at 53rd Street. At 54th Street, the road enters the Sutton Place Tunnel, which passes under apartment buildings on the east side of Sutton Place and York Avenue until 60th Street. In this tunnel, the southbound roadway is raised and runs over the northbound roadway for northbound access to and from the Queensboro Bridge interchange (exit 12). As part of the design in this area, numerous homes on the river were demolished and rebuilt or otherwise modified to accommodate the highway. At 63rd Street, the southbound lanes descend to ground level, at the same elevation as the northbound lanes.
From 63rd to 71st Streets, the FDR Drive passes under a series of interconnected at-grade tunnels. The segment from 63rd to 68th Street runs under an annex constructed by Rockefeller University, while the section of roadway between 68th and 71st Streets runs underneath the pilotis of the New York-Presbyterian Hospital. Afterward, the FDR Drive continues north at ground level. There is a southbound-only entrance and exit, labeled exit 13, at 71st–73rd Streets, serving Lenox Hill on the Upper East Side. Another southbound-only entrance exists at 79th Street; there is no exit from either direction, nor is there any exit number reserved for this interchange. From 81st to 90th streets runs a final, enclosed double-decker structure. The southbound roadway is again raised over the northbound roadway in a short segment of the tunnel between 81st and 86th Streets. The promenade of Carl Schurz Park was built over the highway in 1939, near Gracie Mansion, the New York City mayor’s residence. There is a southbound entrance to the FDR Drive at the intersection of 92nd Street and York Avenue. York Avenue then parallels the FDR Drive until 96th Street, where York Avenue ends. The FDR Drive ascends onto a short elevated viaduct over the 96th Street interchange (exit 14) then descends to street level again. The remaining portion of the FDR Drive to the 125th Street interchange (exit 19) is at grade, passing through East Harlem. There is a southbound-only entrance at 102nd Street, as well as a southbound-only exit at 106th Street, labeled exit 15. At 116th Street, there is another southbound-only exit and entrance numbered exit 16. When the FDR Drive reaches 120th Street, there are three northbound exits in quick succession: exit 17 for the Robert F. Kennedy Bridge, exit 18 for the Willis Avenue Bridge, and exit 19 for 125th Street. Exit 17 also contains a southbound exit and entrance to and from the Robert F. Kennedy Bridge, and exit 19 also hosts a southbound entrance. The FDR Drive transitions into the Harlem River Drive and continues north after 125th Street.
