PennDOT announced a $95 million project to replace the Commercial Street Bridge along Parkway East in Pittsburgh.

The project includes a 25-day road closure starting July 10, during which a new 830-foot-long, 60-foot-high bridge will be constructed and slid into place. Additional work during the closure includes asphalt repair and highway lighting repairs between the Squirrel Hill tunnel and the turnpike.

Local and interstate detours and carpool sites have been established to manage traffic. Three alternate routes have also been established from Monroeville to the airport, downtown and the South Hills. Turn-by-turn detour directions have been provided by PennDOT.
