I-180 begins along the banks of the West Branch Susquehanna River in Williamsport, at an interchange with U.S. Route 15 and U.S. Route 220. The highway begins its signage, concurrent along these routes.

At exit 27B, US 15 leaves the overlap and I-180 continues eastward concurrent with US 220 northbound. From there, I-180 runs along the West Branch Susquehanna River until the highway reaches the eastern suburbs of Williamsport, where US 220 leaves the interstate via exit 15.

From US 220 to the eastern terminus, I-180 is aligned north-south, though the highway is signed east-west. The interstate terminates interchanging Interstate 80 and continues as Pennsylvania Route 147.
