The Lehigh Navigation (referred to as the Lehigh Canal) was constructed to carry anthracite coal from the upper Lehigh Valley to Easton. The Lehigh Canal extended from White Haven to Easton. The Lehigh Canal system generated a great deal of industrial development in the form of mining and the accompanying infrastructure. It gave rise to many towns and offshoot businesses: timber cutting and sawmills; steel and silk mills; and one of the largest tanneries in the U.S., to name only a few businesses that once thrived here. Today, you will find watered sections and walking trails at Weissport, Walnutport, Allentown, Bethlehem, Freemansburg and Easton.
