Flint Hill Road Closed Due to Sinkhole in Upper Merion Township


King of Prussia, PA – The Pennsylvania Department of Transportation (PennDOT) announced today that Flint Hill Road is closed between Church Road and Hertzog Boulevard in Upper Merion Township, Montgomery County, due to a sinkhole.

During the closure, Flint Hill Road motorists are directed to use Church Road, Feheley Drive, and Hertzog Boulevard.

Flint Hill Road will remain closed until PennDOT engineers can further assess the extent of the damage and develop a plan to repair and safely reopen the highway.

Drivers are advised to allow extra time when traveling near the work area because slowdowns will occur.
