Authorities are closing the George C. Platt Memorial Bridge for three days so crews can complete maintenance work.
The Platt Bridge, which takes drivers along Route 291 across the Schuylkill River in southwest Philly, will close at 8 p.m. Friday and will reopen Monday at 5 a.m.
Detours will be in effect.
For travelers heading eastbound, follow Island Avenue to Enterprise Avenue to I-95 North to Broad Street to Pattison Avenue to Route 291.
Drivers heading westbound should follow Pattison Avenue to Broad Street to I-95 south to Enterprise Avnue to Island Avenue to Route 291.
PennDOT suggests padding travel time.
During the closure, crews will place an epoxy overlay on the western end of the bridge to protect the surface and prevent moisture from developing, according to PennDOT officials.
This job is part of a $42.8 million project to preserve the Platt Bridge. Officials expect to complete the work in July.
