The Calhoun Street Toll Supported Bridge (also known as the Trenton City Bridge[1]) is a historic bridge connecting Calhoun Street in Trenton, New Jersey across the Delaware River to East Trenton Avenue in Morrisville, Bucks County, Pennsylvania, United States.

[4] The bridge was part of the Lincoln Highway until 1920 (when the highway was moved to the free Lower Trenton Bridge), and was later connected to Brunswick Circle by the Calhoun Street Extension as part of a bypass of downtown Trenton.

Before 1940, trolleys of the Trenton-Princeton Traction Company, utilized this bridge to cross into Pennsylvania.

[5] On May 24, 2010, the bridge completely closed to vehicular and pedestrian traffic to undergo much-needed renovations including truss repair and repainting, deck replacement, and repair of approaches.

Currently, the bridge is limited to 3 short tons (2.7 t) at 15 miles per hour (24 km/h) with a clearance of 8 feet (2.4 m).
