Interstate 180 (abbreviated I-180) is a spur highway that connects Williamsport, Pennsylvania to Interstate 80 near Milton, Pennsylvania. The length of the highway is 28.85 miles (46.43 km). It was also the designation of present-day Interstate 176 between Morgantown, Pennsylvania and Reading, when the Pennsylvania Turnpike carried the "I-80S" designation in the 1960s. It is signed as an east–west route for its entire length, even though half of the route runs north–south.

Route description[edit]

Looking west from the Carl E. Stotz Memorial Little League Bridge in Williamsport

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 27A, US 15 leaves the overlap running south across the Carl E. Stotz Memorial Little League Bridge and I-180 continues eastward, still 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. I-180 terminates interchanging Interstate 80 and the freeway continues as Pennsylvania Route 147.
