Interstate 376

Interstate 376 is an east-west interstate highway spur route that lies entirely within Allegheny County, Pennsylvania. It is the primary access route between Pittsburgh and its eastern suburbs, and is locally known as "Parkway East".

The highway is about 14 miles long, terminating in downtown Pittsburgh at Interstate 279 and at Monroeville, Pennsylvania at Interstate 76 (the Pennsylvania Turnpike) and U.S. Highway 22. I-376 is connected to the southern end of Interstate 579 by the Boulevard of Allies.

I-376 is a total of six lanes for most of its length. However, it is only four lanes through the Squirrel Hill Tunnel , a major cause of congestion.
