    ​U.S. 202 (Dekalb Pike) ​​Sinkhole Remediation Project​​

    Project Overview

    County: Montgomery
    Municipality: Upper Merion Township
    State Route(s): U.S. 202
    Local Name(s): Dekalb Pike
    Project Type: Sinkhole Remediation
    Last Updated: November 2025

    The U.S. 202 (Dekalb Pike) sinkhole remediation project will provide a long-term solution to address repeat sinkholes that have occurred within the roadways. The proposed work will be completed along U.S. 202 (DeKalb Pike) in Upper Merion Township, Montgomery County between Henderson Road and Saulin Boulevard. The proposed scope of work includes a limited mobility grouting program that will involve drilling 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 reduce the risk of future sinkholes. Additional proposed work for this project includes drainage pipe replacement and pavement reconstruction.

    Construction Update

    PA American Water will be performing a water main relocation on U.S. 202 South (Dekalb Pike) for several weeks under this $22.4 million project to remediate sinkholes on U.S. 202 (Dekalb Pike) in Upper Merion Township, Montgomery County.

    Motorists are advised of the following travel restriction:

    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.

    PennDOT conducted public outreach to adjacent owners and businesses and will continue to coordinate construction activities to maintain access to all connecting properties.
