The Tacony–Palmyra Bridge is a combination steel arch, double-leaf bascule bridge across the Delaware River, connecting New Jersey Route 73 in Palmyra, New Jersey and Pennsylvania Route 73 in the Tacony section of Philadelphia. Paralleling the "Betsy Ross Bridge" also across the upper Delaware River, the Tacony–Palmyra Bridge has a total length of 3,659 feet (1,115 m) and spans 2,324 feet (708 m). It was designed by Polish-born architect, Ralph Modjeski, (1861-1940). After one and a half years of construction, it opened in 1929 to replace the local river ferry service. Though it opened originally as a four-lane bridge, the lanes were reduced in a 1996–97 1½-year bridge deck-replacement/renovation project to contain now three wider lanes (two toll lanes northwestward into the City of Philadelphia, and one free lane southeastward into the State of New Jersey). The bascule draw span is located immediately southeast of the main, arched span over the shipping/boating channel to allow passing maritime traffic. It is one of the few drawbridges to not have gates blocking traffic when the span is raised.
The Bridge is owned and maintained by the Burlington County Bridge Commission of New Jersey. The bridge has a $4 toll as of September 15, 2015[update], which is discounted to $3 if the toll is paid using the "E-ZPass" system. Despite interruptions due to occasional openings for passing shipping traffic (the upper Delaware River is navigable as far north as Van Sciver Lake near Bristol, Pennsylvania), it serves as a lower-cost alternative to the six-lane, high-span Betsy Ross Bridge, of 1969-1974, further south paralleling the Tacony-Palmyra, which there charges $5 for the westward crossing.
A walkway on the Tacony–Palmyra Bridge is open to pedestrian and bicycle traffic, plus taking advantage of the river scenery.
On October 10, 2013, the drawbridge became stuck in the open position when a roller under the maintenance walkway seized, causing it to jam and the bridge to stop moving. The Tacony–Palmyra was closed for approximately eleven hours total.
