The George C. Platt Memorial Bridge is a through truss bridge that carries PA 291 (Penrose Avenue) over the Schuylkill River in Southwest Philadelphia, Pennsylvania. It was opened to traffic in 1951, replacing a swing bridge to the south which carried Penrose Ferry Road across the river. Originally called the Penrose Avenue Bridge, it was renamed in 1979 to honor Civil War hero George Crawford Platt (1842–1912). Today, the Platt Bridge is a key arterial route which carries an average of 56,000 vehicles daily.
