The only canal of the Susquehanna Division of the Pennsylvania Canal ran 41 miles (66 km) along the west bank of the main stem of the Susquehanna River between a lock near the mouth of the Juniata River and the canal basin at Northumberland. Meeting the West Branch Canal and the North Branch Canal at Northumberland, it formed a link between the public and private canals upriver and the east–west Pennsylvania Canal and rail route known as the Main Line of Public Works.
