FDR Drive

The FDR Drive is a 9.44-mile freeway-standard parkway on the east side of the New York City borough of Manhattan. It starts just north of the Battery Park Underpass at South and Broad Streets and runs along the entire length of the East River, from the Battery Park Underpass under Battery Park – north of which it is the South Street Viaduct – north to 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 , an unsigned reference route.
The highway is mostly three lanes in each direction, with the exception of a small section underneath the Brooklyn Bridge where it is one lane in each direction and a section near the Queensboro Bridge interchange where there are only two lanes going northbound.
