Ouachita River Bridge, Spanning Ouachita River at U.S. Highway 167, Calion, Union County, AR

Significance: The Ouachita River Bridge at Calion is a good example of the cantilever design used in Arkansas in the late 1920s and early 1930s. The bridge is also significant because it united the southeastern and southwestern quarters of Arkansas, which the Ouachita River separated. It also opened a direct route from Little Rock to El Dorado.
