Reconstruction

As part of a major NYCDOT reconstruction project from 2001-2005, a new swing span was floated into place on October 29, 2004. Two lanes of Manhattan-bound traffic opened on December 6, 2004, and the remaining three lanes opened in 2005. In addition to replacing the swing span and its machinery, the project included redesigned approach ramps to the bridge on the Bronx side and off the bridge in Manhattan. As reconstructed, the Third Avenue Bridge carries five lanes of Manhattan-bound traffic from the Bronx, which split to three ramps in Manhattan: to East 128th Street and Second Avenue; to Lexington Avenue and East 129th Street; and to the southbound Harlem River Drive/
