The Freeport Rail Bridge is a truss bridge that carries the Norfolk Southern Railway across the Allegheny River between Freeport and Allegheny Township in Pennsylvania. A structure originally created on this site by the Pennsylvania Railroad as part of their West Penn Line in 1866. In 1895, the railroad replaced this bridge; the third and current incarnation was completed in 1950, along with new approach ramps that eliminated a narrow tunnel.
