    ​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: June 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.

    Temporary traffic control patterns have been implemented to provide a safe work zone during construction. U.S. 202 will utilize a staged-partial traffic detour to maintain traffic in a single direction on U.S. 202. Opposing traffic will be diverted to Saulin Boulevard and Henderson Road. 

    Beginning Monday, February 24, through late September, northbound U.S. 202 (Dekalb Pike) will be closed 24/7 between Henderson Road and Saulin Boulevard/Prince Frederick Boulevard. During the closure, motorists are directed to use Henderson Road and Saulin Boulevard. 

    Drivers are advised to allow extra time when traveling near the work area because significant backups and delays will occur. 

    Once northbound U.S. 202 (Dekalb Pike) construction is completed, work will shift to reconstruct southbound U.S. 202 (Dekalb Pike) through the same work area sometime in early 2026.

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

    Work this spring and summer will focus on grouting and drilling to fill the voids beneath northbound U.S. 202 (Dekalb Pike).

    Here are construction photos from the operations in June.
