The Tacony–Palmyra Bridge is a combination steel tied-arch and double-leaf bascule bridge across the Delaware River that connects New Jersey Route 73 in Palmyra, New Jersey with Pennsylvania Route 73 in the Tacony section of Philadelphia. The bridge, designed by Polish-born architect Ralph Modjeski, has a total length of 3,659 feet (1,115 m) and spans 2,324 feet (708 m). After one and a half years of construction, it opened on August 14, 1929, replacing ferry service that had operated between Tacony and Palmyra since May 6, 1922.
