The Calhoun Street Toll Supported Bridge (aka 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 Brunswick Circle by the Calhoun Street Extension as part of a bypass of downtown Trenton.
