The bridge carrying U.S. Route 20 over the Vermilion River was constructed in 1933 and is considered eligible for listing in the National Register of Historic Places as an example of the Ohio Department of Highways Bureau of Bridges' aesthetically detailed, open spandrel, concrete arch structures. Designed by William E. Burroughs of the bureau and constructed by the Hecker-Moon Company of Cleveland at a cost of $57,742.55, it reflected the Department of Highways' Great Depression practice of erecting bridges that were aesthetically pleasing and labor-intensive, providing employment for skilled workers such as carpenters who built the falsework into which the concrete was poured. Its twin ribbed arch measured 154 feet in length, and it shows the department's major influence on the state's concrete bridge designs. Although the original decorative railings, sidewalks, and deck were replaced in the 1980s, the classically detailed columns and sub-deck arcading still express the unique circumstances that dominated bridge building during the 1930s. Advances in steel-reinforced concrete at the beginning of the 20th century allowed the development of open spandrel bridges with graceful visual appeal for scenic and prominent locations, and this bridge shows how such structures became more skeletal and refined by the mid-1930s. An earlier Ohio Department of Highways open spandrel arch, built in 1929 in Fitchville on U.S. 250, also crossed the Vermilion River.
