The Manayunk Bridge (a.k.a. Manayunk Viaduct) is an S-shaped former railroad bridge over the Schuylkill River, Schuylkill Canal and Schuylkill Expressway, that connects Bala Cynwyd, Montgomery County and the Manayunk neighborhood of Philadelphia, Pennsylvania. Closed to rail traffic in 1986, it is now an extension of the Cynwyd Heritage Trail (along the river's right bank) and connects to the Schuylkill River Trail (along the left bank).
