UPPER CHICHESTER TWP, PA — Drivers traveling on U.S. 322 (Conchester Highway) in Delaware County should prepare for significant delays through December 21 as the Pennsylvania Department of Transportation (PennDOT) implements around-the-clock lane closures in both directions for median construction in Upper Chichester Township.
At a Glance
- Roads Affected: U.S. 322 (Conchester Highway) in both directions between I-95 and Route 452 (Market Street); Bethel Avenue between the U.S. 322 overpass and Keystone Road.
- Dates: Through Monday, December 21, 2026; westbound U.S. 322.
- Times: U.S. 322 closures, 24 hours a day, seven days a week; Bethel Avenue, 8:00 AM–4:00 PM on weekdays.
- Reason: Median construction and utility improvements.
The continuous lane closures on U.S. 322 will affect eastbound and westbound traffic between the I-95 and Route 452 interchanges. Periodic weekday lane closures with flagging will also affect Bethel Avenue during utility construction.
The restrictions are part of PennDOT’s $63.4 million project to replace the U.S. 322 bridge over the CSX Railroad and improve approximately one mile of the highway and adjacent Bethel Road.
The project is the third of four construction contracts under PennDOT’s broader U.S. 322 Improvement program, which targets 6.7 miles of highway through Concord, Bethel, and Upper Chichester townships.
PennDOT warns that backups and delays will occur. Motorists should allow additional travel time and consider alternate routes. All scheduled work is weather dependent.
