322 Conchester Highway


U.S. 322 (Conchester Highway) Improvement Project

Welcome to us322conchester.com. Phase one construction (Section 101) to double the capacity and improve safety on U.S. 322 (Conchester Highway) in southwestern Delaware County  between U.S. 1 (Baltimore Pike) and Clayton Park Drive in Concord Township wrapped up in late 2020.

Under the much anticipated U.S. 322 (Conchester Highway) Improvement Project, PennDOT is widening, rebuilding, and in places, realigning U.S. 322 (Conchester Highway), and improving 15 intersections and two interchanges along a well-traveled, corridor extending 6.7 miles from U.S. 1 (Baltimore Pike) to just east of Route 452 (Market Street) in Concord, Bethel and Upper Chichester townships. The improvements will be completed under four main construction contracts, Section 101, Section 102, Section 103, and Section CSX.

The project addresses the immediate issues of traffic congestion and safety by widening U.S. 322 (Conchester Highway) from two-lanes-to-four, by separating eastbound from westbound traffic with a grass median, and by managing access with improvements to the intersections that channel traffic to and from the busy arterial.

Section 10 widened U.S. 322 (Conchester Highway) from two-to-four lanes, with eastbound and westbound traffic separated by a grass median and turn lanes at intersections, from U.S. 1 (Baltimore Pike) in Concord Township to just east of Clayton Park Drive in Bethel Township. Nine intersections within the Section 101 work area were reconstructed and/or improved.

Section 102, scheduled for construction in 2024, and Section 103, scheduled for construction in 2022, will widen U.S. 322 (Conchester Highway) from two-to-four lanes, with eastbound and westbound traffic separated by a grass median, from east of Clayton Park Drive in Bethel Township to Cherry Tree Lane in Upper Chichester Townsnship. The existing four lane segment of U.S. 322 (Conchester Highway) from Cherry Tree Lane to just east of the Route 452 (Market Street) Interchange also will be reconstructed. Six intersections within Section 102 as well as the Foulk Road and Route 452 (Market Street) interchanges will be rebuilt and improved.

In addition to Sections 101, 102 and 103, PennDOT will replace the bridge carrying U.S. 322 (Conchester Highway) over CSX Railroad and Bethel Road in Upper Chichester Township. The bridge will be replaced under a separate contract that is scheduled for construction beginning in late 2021 or 2022, Section CSX.

A separate contract Section MIT, started in late 2016, developed a site for relocating a PennDOT maintenance yard and constructed replacement wetlands for the U.S. 322 (Conchester Highway) corridor. Section MIT was completed in the spring of 2019. PennDOT will finish construction of the maintenance yard in a separate contract scheduled for 2021.
