By the 1820s, the Potomac River had become silted up and was not navigable up to Georgetown. Construction of the Chesapeake & Ohio Canal began in July 1828, to link Georgetown to Harper's Ferry, Virginia (West Virginia after 1863). But the canal was soon in a race with the Baltimore & Ohio Railroad and got to Cumberland eight years after the railroad, a faster mode of transport, and at the cost of $77,041,586. It was never profitable. From its beginning to December 1876, the canal earned $35,659,055 in revenue, while expending $35,746,301.
