History

Glenwood bridge (1894)

The original bridge was built by the Penn Bridge Company of Beaver Falls[2] and carried trolley tracks between Pittsburgh and Homestead. It was later paved with wood to allow vehicle traffic to share the crossing.[3] Permission was given by the Public Utilities Commission on November 8, 1962 for Pittsburgh Railways to convert trolley routes 55 East Pittsburgh via Homestead and Braddock and 98 Glassport to bus service, as the replacement bridge planned did not incorporate trolley tracks.[4] Trolley service 55 across the bridge ended on July 4, 1964.[5]

South interchange

At the southern end of the bridge is an expressway-style interchange with Pennsylvania Route 837.[6] This interchange was built for a spur of the cancelled "East-West Expressway", which was at the proposal stage when the bridge was built.[7][8]
