Erie to Pittsburgh Trail

The Erie to Pittsburgh Trail is a rail trail being developed between Erie and Pittsburgh in Western Pennsylvania and Western New York. It will connect to the Great Allegheny Passage, creating a 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 and Kennerdell Tunnel. 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.
