Built in 1877 and spanning approximately ninety-five feet, Stevenson Road Covered Bridge carried vehicular traffic until 2003. It is one of a few Smith truss bridges left in the United States. The Smith Bridge Company manufactured the bridge using various patents secured by its founder, Robert W. Smith. The company originated in Tippecanoe City, Ohio, also known as Tipp City, and later relocated to Toledo. In 1890, the Toledo Bridge Company purchased the company from Smith. Robert Smith died in 1898 at the age of sixty-five, leaving behind a legacy of unique covered bridges.
