PennDOT will begin overnight lane restrictions Monday night on the Parkway East and several nearby roadways in Allegheny County.<\/p>\n
The work is in preparation for the major Commercial Street Bridge replacement project and planned 25-day closure of Parkway East beginning July 10 at 9 p.m..<\/p>\n
The initial overnight restrictions are part of multiple traffic changes leading up to the bridge closure.<\/p>\n
Starting Monday night, a single lane closure on I-376 in each direction will occur between the Edgewood\/Swissvale (Exit 77) and Churchill (Exit 79B) interchanges from 9 p.m. to 5 a.m. each night through Thursday.<\/p>\n
During the single-lane closures, crews will complete preparatory work before the bridge closes.<\/p>\n
Once the bridge closes, I-376 will be reduced to a single lane of traffic in each direction between the Edgewood\/Swissvale (Exit 77) and Wilkinsburg (Exit 78B) interchanges until the bridge reopens.<\/p>\n
In addition to the overnight work on Parkway East, drivers will also encounter long-term lane restrictions on nearby roads.<\/p>\n
Beginning at about 9 p.m. continuous, around-the-clock lane closures will be implemented on:<\/p>\n
Route 30 (Ardmore Boulevard) in each direction between Morrow and Brinton roads The Boulevard of the Allies in each direction between McDevitt Place and the Boulevard of the Allies slip ramp from Fifth Avenue.<\/p>\n
Restrictions will remain until the bridge reopens in early August.<\/p>\n
During these closures, Boulevard of the Allies westbound I-376 will remain open.<\/p>\n
The temporary disruption is part of a larger $95 million project.<\/p>\n
The Commercial Street Bridge replacement project will utilize Accelerated Bridge Construction Techniques to laterally slide the new bridge onto the existing alignment of Parkway East, which would be one of the largest lateral slide projects performed in Pennsylvania.<\/p>\n
The 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 2024 with the reconstruction of the westbound Parkway East off-ramp to Forest Hills\/Wilkinsburg.<\/p>\n
