PROSPECT PARK, Pa. (CBS) -- Delaware County residents will need to adjust their commutes.

The bridge that carries Route 420 South (Wanamaker Avenue) from Prospect Park to Tinicum Township right before Intertstate-95 will be closed indefinitely Wednesday night after an inspection showed significant beam and bearing pedestal deterioration, PennDOT said.

PennDOT said in a release the bridge will remain closed until engineers develop a plan to repair the structure. The project to replace the bridge is near completion and tentatively scheduled for a construction bid in early 2023. 


With the bridge closed, motorists looking to use Route 420 South will be directed to use Chester Pike, Stewart Avenue and northbound I-95 to access Route 420. 

The Route 420 South bridge over Darby Creek was built in 1930. It carries 19,270 vehicles per day, according to PennDOT.

The bridge won't open again until it's completely fixed and passes inspections.
