King of Prussia, PA – The Pennsylvania Department of Transportation (PennDOT) announced today that PA American Water will be performing a water main installation on southbound U.S. 202 (Dekalb Pike) in Upper Merion Township, Montgomery County.
Motorists are advised of the following travel restriction:
Drivers are advised to allow extra time when traveling through the work area because backups and delays will occur. The schedule is weather dependent.
The water main installation is part of advance work before stage 2 of PennDOT’s sinkhole remediation project begins on southbound U.S. 202 (Dekalb Pike) sometime this spring.
PennDOT reopened northbound U.S. 202 (Dekalb Pike) on Tuesday, November 4, 2025, following eight months of construction to repair and reconstruct the roadway.
The ongoing work is part of 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.
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.
