COATESVILLE, PA — Drivers using the Coatesville Downingtown Bypass should prepare for overnight delays next week as PennDOT continues paving work along westbound U.S. 30 in Chester County.
At a Glance
- Roads Affected: Westbound U.S. 30 (Coatesville Downingtown Bypass)
- Dates: June 29-July 1, 2026
- Times: 7:00 PM-5:00 AM the following morning
- Reason: Paving
According to PennDOT, a lane closure will be in place on westbound U.S. 30 between Airport Road and Route 340 (Kings Highway) from Monday, June 29, through Wednesday, July 1.
No detour has been announced, but motorists should expect delays as traffic merges through the active work zone. Plan extra time for travel and seek alternate routes when possible, particularly during evening and overnight hours.
The paving work is part of an ongoing $9.3 million project to improve travel and safety along the western section of the Coatesville Downingtown Bypass. In addition to paving, the project includes milling, base repairs, installation of a new bituminous overlay, replacement of edge-line rumble strips, and refreshed pavement markings to extend the life of the roadway.
The project corridor spans the City of Coatesville and portions of Caln, Sadsbury, Valley, and West Caln townships.
All scheduled activities are weather dependent and may be adjusted if conditions warrant.
Motorists traveling through the area should remain alert for changing traffic patterns, reduced lane capacity, and construction crews working near the roadway.
