Commercial Street Bridge Replacement Project

Plan Ahead: Commercial Street Bridge Replacement

PennDOT will replace the aging Commercial Street Bridge on I-376 Parkway East to improve
safety and mobility for Pittsburgh commuters. To complete this work efficiently,
Accelerated Bridge Construction (ABC) techniques will be used, requiring a full closure of I
376 Parkway East for approximately 25 consecutive days. Expect heavy delays and significant congestion.


Closure Details:

  • Where: I-376 between Squirrel Hill Tunnel and Edgewood/Swissvale (Exit 77)
  • When: July 10 – August 3, 2026* (*dates subject to change)
