PHILADELPHIA (CBS) —  The George C. Platt Memorial Bridge (Route 291) in Southwest Philadelphia will be closed and detoured from 8 p.m. Friday to 5 a.m. Monday to place an epoxy sealer on the bridge deck, the Pennsylvania Department of Transportation said.

Crews will work this weekend to place an epoxy overlay on the western end of the bridge to protect the concrete surface and prevent moisture intrusion.
