Location
New Cumberland Locks and Dam is located on the right descending bank of the Ohio River, just off Ohio State Route 7 at the small town of Stratton, Ohio. Across the river and two miles downstream lies New Cumberland, WV, the originally planned site of the lock and dam, and hence its namesake. The tall stacks and white steam of the coal-fired Ohio Edison Sammis Power Plant between Stratton and neighboring Port Homer tower over the project.

History
New Cumberland navigation project was constructed from 1955 to 1961, with the locks opening for traffic in November 1959. This facility eliminated the original Locks and Dams 7, 8 and 9 which were constructed by the U.S. Army Corps of Engineers between 1904-1914. The three replaced projects each contained a single lock and the old-style wooden wicket dam.

Montgomery averages about 550 commercial lockages every month, plus another 275 lockages of pleasure craft during the busy summer months.
