Commercial Street Bridge Replacement on I-376 between Squirrel Hill Tunnel and Edgewood/Swissvale (Exit 77) beginning July 10th and ending around August 3rd

Starting on July 10th and continuing until August 3rd, PennDOT will replace the aging Commercial Street Bridge on the I-376 Parkway East between Squirrel Hill Tunnel and Edgewood/Swissvale (Exit 77) 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, although additional time may be necessary to allow for completion. This area will be subject to significantly congested traffic and heavy delays until this work is completed.
