    Sinkhole Remediation Planned Next Week on Route 29 (Morehall Road) in East Whiteland Township

    Route 29 (Morehall Road) will remain one lane in each direction through early June 2026

    March 26, 2026

    King of Prussia, PA – The Pennsylvania Department of Transportation (PennDOT) announced today that sinkhole remediation is planned next week on Route 29 (Morehall Road) under the $22.5 million project to provide long-term remediation on Route 29 (Morehall Road) in East Whiteland Township, Chester County, and on U.S. 202 (Dekalb Pike) in Upper Merion Township, Montgomery County.

    Motorists are advised of the following travel restriction:

    Drivers are advised to use an alternate route or allow extra time when traveling through the work area because significant backups and delays will occur.

    Under this project, PennDOT’s contractor will utilize a limited mobility grouting program, which will involve drilling a series of holes through the pavement in a “grid” pattern. Pressurized grout will be injected into the drilled holes to fill subsurface voids beneath the roadway. The filling of subsurface voids will help stabilize the ground beneath the pavement and will reduce the risk of future sinkholes. Additional work includes drainage improvements and pavement reconstruction.

    Remediation of sinkholes on Route 29 (Morehall Road) and U.S. 202 (DeKalb Pike) were deemed necessary for a long-term solution following reoccurring sinkholes and emergency repairs resulting in traffic disruptions along both corridors.

    Heidelberg Materials, LLC of northeast region, is the general contractor on this project, which is financed with 100 percent federal funds.

    For more information, please visit the Route 29 (Morehall Road) and U.S. 202 (Dekalb Pike) sinkhole remediation project pages.
