Pennsylvania Canal (Susquehanna Division)

The Susquehanna Canal of the Pennsylvania Canal System was funded and authorized as part of the 1826 Main Line of Public Works enabling act, and would later become the Susquehanna Division of the Pennsylvania Canal under the Pennsylvania Canal Commission. Constructed early on in America's brief canal age, it formed an integral segment of the water focused transportation system which cut Philadelphia-Pittsburgh (pre-railroad) travel time from nearly a month to just four days.
