Tennessee-Tombigbee Waterway

Two centuries in the making.

The idea of connecting the Tennessee and Tombigbee rivers is older than the United States itself. It took visionaries, engineers, four states, and one of the largest civil works projects in American history to make it real.

From portage trail to marine highway.

  1. 1770s

    An idea older than the nation

    French explorers and early settlers note how close the Tennessee River comes to the headwaters of the Tombigbee: a short portage separating two great river systems, and a shortcut from the interior to the Gulf.

  2. 1874

    The first federal survey

    Army engineers formally study a canal connecting the rivers. The dream has a route, but the technology and the will to build it are still a century away.

  3. 1946

    Congress says yes

    The waterway is finally approved by Congress. Authorization, however, is not appropriation: the fight for funding begins.

  4. 1958

    Four states, one compact

    Congress ratifies the interstate compact creating the Tennessee-Tombigbee Waterway Development Authority: Alabama, Kentucky, Mississippi, and Tennessee, united to see the waterway completed and put to work. The Authority has championed the project ever since.

  5. 1968

    The turning point

    Political momentum builds as President Johnson budgets funds to start engineering and design. The waterway moves from map to blueprint.

  6. 1972

    Construction begins

    With funding included in the President's budget, actual construction begins. Over the next twelve years, crews excavate roughly 310 million cubic yards of earth, more than was moved to build the Panama Canal.

    The last cut is made

    Construction wraps in December 1984: 234 miles of channel, ten locks and dams, and a 27-mile divide cut through the ridge separating the two river basins, one of the largest civil works projects in American history.

    Open for commerce

    The first commercial tows transit the waterway in January 1985, and the corridor celebrates its formal dedication that June. A two-century-old idea is now a working American waterway.

    Marine Highway M-65

    The U.S. Department of Transportation designates the corridor as Marine Highway M-65: more than 1,300 miles spanning five river systems, with TTWDA as the route's official sponsor.

    The promise, delivered

    The waterway continues to support commerce, industry, and recreation. Its story is still being written.
