The Calhoun Street Toll Supported Bridge (also known as the Trenton City Bridge) 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. It was constructed by the Phoenix Bridge Company of Phoenixville, Pennsylvania, in 1884. 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 by the Calhoun Street Extension as part of a bypass of downtown Trenton. Prior to 1940, trolleys of the Trenton-Princeton Traction Company, utilized this bridge to cross into Pennsylvania. The bridge is owned by the Delaware River Joint Toll Bridge Commission, and is maintained with tolls from other bridge
