Traffic Advisory: The full, multi-week closure of I-376 Parkway East begins Friday, July 10. Among several "Local" & "Interstate" detour routes shared by Pennsylvania Department of Transportation (PennDOT), Oakland can expect a predictably high volume of local/interstate traffic navigating through Oakland along Fifth & Forbes Ave as travelers are directed around the construction zone during the 25-day period scheduled to end 8/3/26.
The "Interstate Detour" is one of several routes defined by the PennDOT project team to help mitigate the impact felt by not just commuters, but neighborhood residents.
Of the many options available, inbound travelers heading West on I-376 Parkway East can, for example, follow detour signage to exit I-376 at Wilkinsburg (Exit 78B) to utilize Penn Ave to Fifth Ave through Shadyside and Oakland to ultimately return to Westbound I-376 Parkway East to proceed further into the city; or local traffic can alternately connect to adjacent neighborhoods along the route (PURPLE on the map.)
Eastbound travelers following detour signage will be directed to either exit I-376 at the Forbes Ave/Oakland (Exit 72A) to follow Forbes Ave to Fifth and then Penn Ave to ultimately reconnect with I-376 after the work zone (essentially routing north of the closure – PURPLE); and those who stay on I-376 past Oakland must exit at the Squirrel Hill/Homestead (Exit 74; just before the Tunnel) which will direct motorists along Beechwood Blvd to Browns Hill Rd over Homestead Grays Bridge, E 8th Ave over the Rankin Bridge, and north on to S Braddock Ave to reconnect with I-376 after the work zone (essentially routing south of the closure – PINK on the map.)
For tighter travel around the Frick Park area, PennDOT has also shared a Commercial St/Forbes Ave detour route (BLUE on the map.)
The map illustrations shown here are available on PennDOT's dedicated project page for the I-376 Commercial Street Bridge Replacement Project in image/PDF formats along with Turn-By-Turn Instructions, and also as an Interactive Map.
