Road Closures Announced For 'Urgent' Valley Forge Sewer Repairs

TREDYFFRIN, PA -- Tredyffrin Township sewer upgrades will cause several road closures around Valley Forge National Historical Park beginning April 1. Traffic in neighboring municipalities, including Phoenixville and King of Prussia, could be affected.

The urgent upgrades being performed by the township on lines running through will require some roads to be temporarily closed during construction.

The closures detailed on the map shown below will be in effect through July 31, the park said.

The Wilson Road Force Main, a sanitary sewer pipeline, runs for 3.6 miles through Valley Forge, paralleling Valley Creek and the Schuylkill River. Although the pipe runs through the park, it serves the residents of six municipalities upstream of the park.

The 40-year old pipe has failed three times recently, Tredyffrin Township said, releasing as much as 18 million gallons of untreated sewage into the creek and river.

"These are extremely urgent repairs necessary to protect both the public, and the environment," the park said in a statement.

Route 252 (Valley Forge Road) from the Knox Covered Bridge to Route 23 will be Closed April 1, 2016 through July 31, 2016. The Knox Parking Lot on Route 252 will remain open to park visitors throughout construction.

Yellow Springs Road from Route 252 (Valley Forge Road) to Wilson Road, including the Knox Covered Bridge is currently closed and Will remain closed until July 31, 2016. The Wilson Road Parking Lot will remain open throughout construction. Access to Library Lane and the Philander Chase Knox House will remain open throughout construction.
