Main Line of Public Works

The Main Line of Public Works is a canal network in Pennsylvania designed to move goods and materials across the state. The system includes waterways, aqueducts, and supporting structures that formed an integrated transportation route.

This canal system was built in the early 1800s to support Pennsylvania's economic growth and compete with other states. It represented a major advancement in transportation technology during the Industrial Revolution.

The remains of this system are scattered across Pennsylvania and can be explored on foot at various locations. Visitors can find surviving sections of the original canals and structures that give a sense of the historic route.

This system was one of the most ambitious transportation projects of its era, attempting to compete with the famous Erie Canal in New York. Though it did not achieve the same level of success as its northern rival, it left lasting marks on Pennsylvania's landscape.
