The FDR Drive (officially referred to as the Franklin D. Roosevelt East River Drive, and sometimes known as the FDR) is a 9.44-mile (15.19 km) 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 / Triborough Bridge exit, 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 highway is mostly three lanes in each direction, with the exception of a small section underneath the Brooklyn Bridge where it is two lanes southbound and one lane northbound. A section between the Queensboro Bridge/60/61st Street interchange is also narrowed to two lanes. 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 of clearance and weight issues. All commercial vehicles (including trucks) are banned from all sections of the FDR Drive. The FDR Drive features a mix of below-grade, at-grade, and elevated sections, as well as three partially covered tunnels.
