PennDOT District 11 is announcing the closure of an eastbound (outbound) I-376 (Parkway East) on-ramp in the City of Pittsburgh, Allegheny County, will occur Thursday and Friday, May 29-30 weather permitting.
A full closure of the Beechwood Boulevard on-ramp to eastbound (outbound) I-376 will occur from 5 a.m. until 2 p.m. Thursday and Friday. The ramp closure will occur in conjunction with the single-lane restriction currently in place on eastbound I-376 between the Squirrel Hill Tunnel and the Edgewood/Swissvale (Exit 77) interchange. Traffic will be detoured.

This ramp closure is expected to continue in conjunction with the eastbound I-376 single-lane closures.
Crews will construct a retaining wall on I-376 outside of the Squirrel Hill Tunnel near the site of the new Commercial Street Bridge.
The Commercial Street Bridge replacement project will utilize Accelerated Bridge Construction Techniques to laterally slide the new bridge onto the existing alignment of I-376 (Parkway East), which would be 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 Swissvale Borough 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). Additional work last season included the temporary relocation of Commercial Street and the Nine Mile Run Trail below the bridge, the relocation of sanitary sewer lines, and portions of phased ITS work. Work in 2025 includes the installation of new sign structures, temporary and permanent piers, abutments, and piles for temporary and permanent foundations, steel erection, and the continuation of phased ITS work. In 2025, nine overnight full closures and detours of eastbound I-376, a full weekend closure and detour of I-376 in each direction, and 35 extended weeknight single-lane restrictions on eastbound I-376 will occur. In 2026, motorists can expect a 25-day full closure and detour of I-376. The overall project is anticipated to conclude in the summer of 2027.
