UPPER CHICHESTER TWP, PA — Motorists traveling U.S. 322 (Conchester Highway) and Route 452 (Market Street) in Upper Chichester Township should prepare for periodic overnight lane closures through the end of 2027 as the Pennsylvania Department of Transportation (PennDOT) advances a $99.4 million project to widen the highway and improve traffic safety in Delaware County.
At a Glance
- Roads Affected: U.S. 322 (Conchester Highway) between Chelsea Parkway and Bethel Avenue; Route 452 (Market Street) between Meetinghouse Road and Story Road.
- Dates: Periodic restrictions through December 2027.
- Times: 7:00 PM–6:00 AM the following morning.
- Reason: Roadway reconstruction, highway widening and interchange improvements.
Drivers will encounter intermittent nighttime lane closures along both corridors as crews reconstruct pavement, widen travel lanes and modify intersections. PennDOT advises motorists to allow extra travel time through the construction areas.
The work is part of the U.S. 322 Section 103 project, which will reconstruct and widen approximately 1.4 miles of Conchester Highway, including converting an existing two-lane section into a four-lane roadway.
Improvements include upgraded traffic signals, additional turning lanes and a realigned Cherry Tree Road/Bethel Avenue intersection.
Crews will also reconstruct pavement and widen shoulders along the existing four-lane section east of Cherry Tree Road toward the CSX railroad bridge at Bethel Road.
At the U.S. 322/Route 452 interchange, the project will reconfigure the roadway connections, add turning lanes and construct ramps from a widened Bethel Avenue.
Section 103 represents the second of four construction projects planned to widen and improve approximately 6.7 miles of U.S. 322 through Concord, Bethel and Upper Chichester townships.
All scheduled construction activities are weather dependent.
