    Sinkhole Remediation Project Begins February 25 on U.S. 202 South (Dekalb Pike) in Upper Merion Township

    U.S. 202 South will be closed and detoured through late fall 2026

     

    February 09, 2026

    King of Prussia, PA – The Pennsylvania Department of Transportation (PennDOT) announced today that Stage 2 construction will begin on Wednesday, February 25, to repair and reconstruct southbound U.S. 202 (Dekalb Pike) under a $22.4 million project to provide long-term sinkhole remediation on U.S. 202 (Dekalb Pike) in Upper Merion Township, Montgomery County, and on Route 29 (Morehall Road) in East Whiteland Township, Chester County.

    Motorists are advised of the following travel restriction:

    During the closure, motorists will be directed to use Saulin Boulevard and Henderson Road. Local access will be maintained at all times to residences and businesses.

    PennDOT reopened northbound U.S. 202 North (Dekalb Pike) between Henderson Road and Saulin Boulevard on Tuesday, November 4, 2025, following eight months of construction to repair and remediate sinkholes under Stage 1 of the project.

    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 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.
