Pittsburgh Parkway East Closure: What To Know

Here's your Patch guide to the gridlock expected when the Parkway East closes for at least five weeks beginning Friday night.

(PennDOT )

PITTSBURGH, PA — Question: Where do you put 100,000 displaced motorists daily when you close a major highway?

Answer: Pittsburgh is about to find out.

Beginning Friday night, a key section of the Parkway East between the eastern end of the Squirrel Hill Tunnel and the Edgewood/Swissvale exit will close until Aug. 5.

PROJECT OVERVIEW

The closure is necessary because of the $95 million Commercial Street bridge replacement project. The old bridge will be demolished and its replacement - which was built in Frick Park adjacent to the existing span-will laterally slide onto the existing parkway alignment.

The Commercial Street Bridge project is one of the largest lateral slide projects ever performed in Pennsylvania.

PennDOTi is warning that heavy delays will occur on detour routes and advises people to work from home or use alternate routes as able.

The agency also is advising people to carpool with a friend or connect with PRT bus or Westmoreland Transit Service to reduce closure traffic. To find a location, click "Resources"at this link.
