The Lehigh Gap or Lehigh Water Gap is a water gap located in the townships of Lehigh, Washington, Lower Towamensing, and East Penn in the Lehigh Valley and Coal Region regions of eastern Pennsylvania. It was formed by the Lehigh River, where it cuts through the Blue Mountain in Pennsylvania. The gap allows easy travel between Carbon County to the north and Lehigh and Northampton counties to the south of the mountain. One of the gap's more distinctive features is Devil's Pulpit, a rock formation that reminds hikers of a church pulpit. Lehigh Gap is also the name of a village once known as Weider's Crossing at the south end of the gap in Lehigh and Northampton Counties.

The Lehigh Canal is a navigable canal that begins at the mouth of Nesquehoning Creek on the Lehigh River in the Lehigh Valley and Northeastern regions of Pennsylvania. It was built in two sections over a span of 20 years beginning in 1818. The lower section spanned the distance between Easton and present-day Jim Thorpe. In Easton, the canal met the Pennylvania Canal's Delaware Division and Morris Canals, which allowed anthracite coal and other goods to be transported further up the U.S. East Coast. At its height, the Lehigh Canal was 72 miles (116 km) long. Although the canal was used to transport a variety of products, its most significant cargo was anthracite coal, the highest quality energy source then available in the United States, and pig iron, a vital input product used in manufacturing steel. Both proved cornerstones of the Lehigh Valley's ascent as a central hub of the American Industrial Revolution, and their mining and transportation defined the rugged blue collar character of the Lehigh Valley towns that surrounded the canal.The route initially consisted of canals and dammed-off sections of the Lehigh River. Boatmen had to navigate barges periodically from the canal through a lock onto the river or vice versa. This design saved time and money and made the canal functional while it was being built, although it made for a slower, more difficult trip for canal-boat captains.
