Description 

The canal starts at Georgetown,DC and runs through Montgomery, Frederick, Washington, & Allegany counties in Maryland.

This 184 mile canal was built between 1828 & 1850 and was used until 1924. It has an elevation change of 605 feet, 75 locks, 7 diversion dams to supply water, and the Paw Paw tunnel at 3,117 feet long. Originally estimated to cost between 4.5 & 8 Million dollars, it ended up costing 11 million. The canal was sold to the federal government in 1938 and in 1971 it became a National Historic Park. The towpath is now a hiking & biking trail.
