King of Prussia, PA – The Pennsylvania Department of Transportation (PennDOT) announced today that PA American Water will be performing a water main relocation on U.S. 202 South (Dekalb Pike) in Upper Merion Township, Montgomery County, under a $22.4 million project to remediate sinkholes on U.S. 202 (Dekalb Pike), and on Route 29 (Morehall Road) in East Whiteland Township, Chester County.
Motorists are advised of the following travel restriction:
- Monday, November 17, through Friday, January 9, from 8:00 PM to 6:00 AM the following morning, a weeknight lane closure will be in place on U.S. 202 (Dekalb Pike) in both directions between Henderson Road and Saulin Boulevard.
During this operation, one lane of through-traffic in each direction will use the newly completed northbound lanes through the work area. Local access will be maintained at all times.
PennDOT reopened U.S. 202 North (Dekalb Pike) on Tuesday, November 4, following eight months of construction to repair and reconstruct the roadway.
The water main relocation is part of advance work before stage 2 of the sinkhole remediation project begins on U.S. 202 South (Dekalb Pike) in early 2026.
Under this project, PennDOT’s contractor is utilizing a limited mobility grouting program, which involves drilling a series of holes through the pavement in a “grid” pattern. Pressurized grout is injected into the drilled holes to fill subsurface voids beneath the roadway. The filling of subsurface voids helps to stabilize the ground beneath the pavement to reduce the risk of future sinkholes. Additional work includes drainage improvements and pavement reconstruction.
Remediation of sinkholes on U.S. 202 (Dekalb Pike) and Route 29 (Morehall Road) were deemed necessary for a long-term solution following reoccurring sinkholes and emergency repairs resulting in traffic disruptions along both corridors.
