King of Prussia, PA – The Pennsylvania Department of Transportation (PennDOT) announced today that the bridge carrying Swamp Creek Road over Unami Creek in Marlborough Township, Montgomery County, was closed today after a bridge inspection determined significant undermining of the substructure following recent storms.

During the closure, Swamp Creek Road motorists will be directed to use Geryville Pike, Route 63 (Sumneytown Pike), Route 563 (Ridge Road), and Whites Mill Road.

The single-lane bridge will remain closed until PennDOT bridge engineers can determine the full extent of the damage and develop a plan to repair and reopen the structure.

Built in 1910, the 98-foot-long, three-span, stone masonry arch deck bridge carries approximately 336 vehicles per day.

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 1,000 traffic cameras.
