Stretching 184.5 miles along the Potomac River between Washington, D.C. and Cumberland, Maryland, the Chesapeake and Ohio Canal National Historical Park preserves remains of America's colorful canal era. For nearly a century, the C&O Canal was the lifeline for communities and businesses along the Potomac, as coal, lumber, grain, and other agricultural products gently floated down the canal to market. This magnificent water highway linked the rapidly growing west to the east and played an important role in the growth and development of our country.
The construction of Chesapeake and Ohio Canal started on July 4, 1828 and lasted for 22 years. The canal was completed on October 10, 1850 at a cost of about $14 million. The canal was 184.5 miles long, 6 feet deep and 60-80 feet wide. There were 74 lift locks built on the canal, 7 dams and 11 aqueducts. One of the most impressive features of the canal, the Paw Paw Tunnel is 3,118 feet long; 27 feet wide and 24 feet high. The canal was in operation from 1850 to 1924. In 1938 the government acquired the approximately 12,000 acres of land adjacent to the canal and Chesapeake and Ohio Canal National Historical Park was established in 1971.
