Erie to Pittsburgh Trail

The Erie to Pittsburgh Trail is a 270 mi rail trail being developed between Erie and Pittsburgh in Western Pennsylvania and Western New York. It will connect to the Great Allegheny Passage (GAP), creating a 605 mi off-road route between Erie and Washington, D.C. via the GAP and the C&O Canal. It will also connect to the Erie Canal trail via New York Bike Route 517 along Lake Erie.

There are two tunnels on the trail's route: Rockland Tunnel (2868 ft) and Kennerdell Tunnel (3350 ft). The Kennerdell Tunnel is one of the longest rail trail tunnels in the United States and among the longest bicycle/pedestrian tunnels in the world.
