After the Pennsylvania Canal Commission smoothed the way, Lehigh Coal & Navigation built the Lehigh and Susquehanna Railroad (L&S) from Pittston to Ashley, building the Ashley Planes inclined railway and linked that by rail from Mountain Top to White Haven at the head of the canal's upper works&mdash;referred to as the "Grand Lehigh Canal"&mdash;which navigations shortened the Lehigh Gorge (now located in the Lehigh Gorge State Park) route, cutting the distance from Philadelphia to Wilkes-Barre and the Wyoming Valley coal deposits by over 100 miles .
