Project Overview


PennDOT is completing improvements to the Markley Street (U.S. 202 South) corridor in Norristown in Spring 2024 with rehabilitation of the historic stone-arch bridge over Stony Creek. The bridge spans diagonally across the intersection of Markley Street and Elm Street.

Preliminary site work got underway in February 2024. Utility relocation begins in March and continues in the spring. Rehabilitation of the bridge itself is scheduled to start in early spring. To complete repairs to the bridge’s structural components, the intersection will be closed and detoured for much of the project’s 12-month duration.

The detour is tentatively scheduled to be in place beginning May 1, 2024.

The project also includes:

  • Reconstruction and widening of Markley Street on both sides of the intersection and pavement adjustments on Elm Street at the intersection.
  • Installation of new, adaptive traffic signals at the intersection of Markley and Elm streets.
  • Relocation of sanitary sewer and water mains at the intersection.
  • New curbs, sidewalks, and ADA curb ramps at the intersection.
  • Installation of new signing and guide rails.

This project follows the completion of Sections 510 (2022) and 530 (2021), which reconstructed Markley Street and constructed the Barbadoes Street connector, respectively. Read more about completed construction here.
