Route 100 Bridge Work to Cause Overnight Closures on U.S. 322 in Chester County

Traffic Advisory

WEST CHESTER, PA — The Pennsylvania Department of Transportation (PennDOT) announced that overnight construction on the Route 100 (Pottstown Pike) bridge, which spans U.S. 322 (West Chester Bypass) in West Goshen Township, Chester County, will continue next week. The superstructure replacement necessitates full closures of the bypass.

On Thursday, July 11, and Sunday, July 14, from 8:00 PM to 6:00 AM the following morning, U.S. 322 will be closed in both directions between Phoenixville Pike and New Street. This construction is part of ongoing efforts to repair damage sustained when a large vehicle struck the bridge on December 21, 2023, causing significant debris to fall onto the roadway.

During the closures, westbound motorists on U.S. 322 will be rerouted via the Paoli Pike Interchange, Gay Street, North High Street, Chestnut Street, Hannum Avenue, and Downingtown Pike. Eastbound travelers will have to use Business U.S. 322, Hannum Avenue, N. New Street, Market Street, West Chester Pike, and the ramp to U.S. 322/U.S. 202 South.

Drivers are urged to plan for additional travel time due to expected backups and delays. These operations are weather-dependent.

The contractor had previously completed emergency repairs to the bridge and the affected section of U.S. 322. This current phase aims to finalize the superstructure replacement, ensuring the long-term safety and functionality of the bridge.

Motorists in the area should remain vigilant and patient as PennDOT works to restore and improve vital infrastructure.
