Williamsburg Bridge

About the Bridge

The Williamsburg Bridge is one of the major crossings of the East River, connecting Manhattan and Brooklyn and serving some of the busiest arteries in New York City. As of 2018, an average of over 104,700 vehicles, 6,700 cyclists and 5,500 pedestrians travel over the Williamsburg Bridge each day.

Bridge Facts

  • Total length: 7,308 feet
  • Main span: 1,600 feet
  • Clearance at center: 135 feet
  • Height of towers: 310 feet
  • Number of cables: 4 cables

  • Total length of wires: 17,500 miles


When it opened in 1903, the Williamsburg Bridge was the longest suspension bridge in the world, carrying rail, trolley, carriages and pedestrians. The Williamsburg Bridge was one of the last major bridges designed for the horse and carriage. By the 1920s, when the automobile became a major mode of transportation, the trolley tracks were replaced with roadways.

The massive stiffening trusses were designed not only to withstand high winds, but also to support rail traffic on the deck. Currently, the bridge carries four two-lane vehicular roadways, a south roadway (inner and outer) and north roadway (inner and outer), with two rapid transit tracks (J, M, and Z subway lines) sandwiched in between. A walkway and a bikeway also run across the bridge.

Current Project

Reconstruction of Williamsburg Bridge and Miscellaneous Rehabilitation

The Williamsburg Bridge rehabilitation program continues under Contract No. 9. The project focuses on structural steel repairs and other miscellaneous rehabilitation. The anticipated completion is Spring 2026.

Project Scope:

  • Structural repairs
  • Seismic retrofit of the main bridge (side spans)
  • Rehabilitation of intermediate towers
  • Partial pavement repairs and anchorage joint replacement


  • Single-lane closures in the Manhattan-bound inner and outer lanes
  • Single-lane closures in the Brooklyn-bound inner and outer lanes
  • Bikeway and walkway are narrowed at the work zones
