PennDOT Improving, Widening U.S. 322 in Delaware County

Two Lanes of U.S. 322 to be Maintained During Peak Travel Times

King of Prussia, PA –  The Pennsylvania Department of Transportation (PennDOT) announced today that preliminary construction began Monday, March 20, on the first of two mainline projects to widen and reconstruct a 6.7-mile section of U.S. 322 (Conchester Highway) from U.S. 1 (Baltimore Pike) to just east of Route 452 (Market Street) in Concord, Bethel and Upper Chichester townships, Delaware County.

This preliminary work is part of a $62.7 million project to improve travel and safety on the first section, or western section of U.S. 322 (Conchester Highway) from U.S. 1 (Baltimore Pike) to just east of Mattson Road/Featherbed Lane near Clayton Park in Concord Township, by widening the highway from two lanes to four lanes with a grass median separating the eastbound and westbound travel lanes.

The scope of work on the first section also includes:

  • Reconstructing, widening and upgrading five intersections to provide four through lanes and turn lanes on U.S. 322 at Evergreen Drive, Fellowship Drive/Station Road, Cambridge Drive, Featherbed Lane/Mattson Road and Clayton Park Drive;
  • Upgrading traffic signals on U.S. 322 at U.S. 1 (Baltimore Pike), Evergreen Drive, Fellowship Drive/Station Road and Featherbed Lane/Mattson Road;
  • Eliminating through and left turn movements on Spring Valley Road, Merion Drive, Cambridge Drive, Station Road and Clayton Park Drive; and
  • Installing three dynamic message signs, six closed circuit TV cameras, and Bluetooth tag readers to optimize traffic flow.

In addition, the bridge carrying U.S. 322 (Conchester Highway) over SEPTA/Webb Creek and the bridge over Smith Bridge Road will be replaced. Five retaining walls and a sound barrier will also be constructed in this section.

During construction, U.S. 322 (Conchester Highway) between U.S. 1 (Baltimore Pike) and Clayton Park Drive will remain open to one lane of traffic in each direction during peak travel times. Periodic flagger-controlled lane restrictions may occur Mondays through Fridays from 9:00 AM to 3:00 PM, and from 7:00 PM to 5:00 AM, for various operations as construction advances along the corridor.

Work on the first mainline section of U.S. 322 (Conchester Highway) is scheduled to be completed in fall 2020.

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.

With construction beginning next week on the western section of U.S. 322 (Conchester Highway), engineering design is advancing for the widening and reconstruction of the eastern section of the highway from Featherbed Lane/Mattson Road to just east of Route 452 (Market Street). Construction on this section is expected to start in 2019.

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 and not yet scheduled for construction.

PennDOT has launched a new website — us322conchester.com — to keep motorists and residents informed during the reconstruction and widening of U.S. 322 (Conchester Highway). The site provides updated construction details and photos, graphics showing improvements at each intersection, travel information for commuters, a form for submitting questions or comments, and an email subscription service for receiving news and other information about the project.

Motorists can check conditions on more than 40,000 roadway miles by visiting www.511PA.com. 511PA, which is free and available 24 hours a day, provides traffic delay warnings, weather forecasts, traffic speed information and access to more than 770 traffic cameras.

511PA is also available through a smartphone application for iPhone and Android devices, by calling 5-1-1, or by following regional Twitter alerts accessible on the 511PA website.
