The Pittsburgh-to-Harrisburg Main Line Canal Greenway™ is a 320-mile corridor that follows the historic path of the Main Line Canal System. It serves as a physical connector that improves opportunities for public access, linkage to important destinations, and economic development. It is not a single, long-distance trail for unimpeded travel, but incorporates the Kiski-Conemaugh and Juniata Rivers Water Trails, and the Roaring Run, West Penn, 6-to-10, and Lower Trails.
