    Commercial Street/Forward Avenue and Trail Short-term Closure Friday Evening, Saturday in Pittsburgh

    October 13, 2026

    Pittsburgh, PA – The Pennsylvania Department of Transportation (PennDOT) is announcing a short-term closure of Commercial Street/Forward Avenue and Nine Mile Run Trail in the City of Pittsburgh, Allegheny County, will occur Friday evening through Saturday evening, October 16-17 weather permitting.

    Commercial Street/Forward Avenue will have a short-term traffic closure between Whipple Street and Summerset Drive from 8:00 PM Friday evening to 8:00 PM Saturday evening. During this time, Nine Mile Run Trail will be closed to all bicycle and pedestrian traffic between the Nine Mile Run parking lot in Swisshelm Park and the Frick Park Commercial Street Parking lot in Squirrel Hill. Traffic will be detoured.

    Crews will perform final paving operations and realign Commercial Street back to its original location. For the safety of the public, the road and trail must be clear of vehicle, bicycle, and pedestrian traffic through the work zone as these operations occur. The restrictions may be lifted earlier if the work is completed sooner.

    The Commercial Street Bridge replacement project utilized Accelerated Bridge Construction Techniques to laterally slide the new bridge in alignment with I-376 (Parkway East), which was one of the largest lateral slide projects performed in Pennsylvania. The $95 million project located between the Edgewood/Swissvale (Exit 77) interchange and Squirrel Hill Tunnel in Edgewood and Swissvale boroughs, and the City of Pittsburgh began in June of 2024 with the reconstruction of the westbound I-376 off-ramp to Forest Hills/Wilkinsburg (Exit 78B). The overall project is anticipated to conclude in the summer of 2027.
