U.S. Route 11 roughly parallels Interstate 81 in the U.S. state of Pennsylvania. It serves Harrisburg and Scranton. Between those two cities, US 11 follows the Susquehanna River, while I-81 follows a shorter route over the mountains.

[edit] Route description

US 11 enters Pennsylvania parallel to I-81 south of Greencastle in Antrim Township, Franklin County. The two routes head to the northeast, running parallel to each other as they pass through Chambersburg, where they intersect U.S. Route 30, Shippensburg, and Carlisle. Northeast of Carlisle in Middlesex, US 11 interchanges with the Pennsylvania Turnpike (Interstate 76) and I-81 in succession. US 11, now to the south of I-81, continues eastward into the western suburbs of Harrisburg as the Carlisle Pike.

In Camp Hill, a close suburb of Harrisburg, US 11 stops paralleling I-81 and joins U.S. Route 15 northward through the western suburbs of Harrisburg. As the road exits the Harrisburg area, US 11 and US 15 begin to parallel the Susquehanna River as both head northward. They intersect U.S. Route 22/U.S. Route 322 near Duncannon and U.S. Route 522 in Selinsgrove. The two routes remain overlapped to an intersection in Shamokin Dam, where US 15 branches off to the northwest, following the path of the Susquehanna's West Branch northward. US 11, in contrast, continues to parallel the main Susquehanna River, passing through municipalities such as Danville, Bloomsburg, and Berwick (where it crosses Interstate 80) prior to reaching Wilkes-Barre.

In Wilkes-Barre, US 11 breaks from the Susquehanna and begins to run parallel to I-81 once more. From Wilkes-Barre, the highway goes through nearby Scranton, becoming the North Scranton Expressway north of downtown. In Clarks Summit, just north of Scranton, US 11 intersects U.S. Route 6. US 6 joins US 11 westward to Factoryville, where US 11 separates from US 6 and resumes its northerly trek through Susquehanna County to the New York-Pennsylvania border in Great Bend Township.
