Cambridge Drive Reopens at U.S. 322

Note: The closure of Merion Drive is postponed until spring 2019.

King of Prussia, PA – Merion Drive will be closed and detoured between Marlborough Lane and U.S. 322 (Conchester Highway) in Concord Township, Delaware County for approximately five months beginning on Monday, December 10, for reconstruction on the eastbound side of the intersection at U.S. 322 (Conchester Highway), the Pennsylvania Department of Transportation (PennDOT) announced today.

During the closure, Merion Drive motorists will be directed to use Marlborough Lane, Cambridge Drive and U.S. 322 (Conchester Highway). Prior to the closure, the Cambridge Drive intersection with U.S. 322 (Conchester Highway) will reopen to traffic. 

The two intersections are among eight being improved under a $62.6 million project to reconstruct, widen and upgrade traffic signals on 2.5 miles of U.S. 322 (Conchester Highway) from U.S 1 (Baltimore Pike) to just east of Featherbed Lane/Mattson Road near Clayton Park.

J.D. Eckman, Inc. of Atglen, Chester County, is the general contractor on the project which is financed with 80 percent federal and 20 percent state funds.

Engineering design is advancing for the widening, reconstruction and other improvements on U.S. 322 (Conchester Highway) from Clayton Park Drive to east of Route 452 (Market Street). Construction on this section (Section 102) is expected to start in late 2020.

An additional contract to replace the U.S. 322 (Conchester Highway) bridge over the CSX railroad and Bethel Road as well as improvements to the adjacent Bethel Road Interchange is under design.
