The Caledonia Bowstring Bridge is a historic bridge in the village of Caledonia, Ohio, United States. Built in the 1870s but no longer in use, it has been named a historic site.In 1873, local officials arranged with the Wrought Iron Bridge Company of Canton, Ohio for the construction of a bowstring arch bridge over the Scioto River. The completed bridge features lattice bracing over the deck, which enabled the design to have both vertical and horizontal support at a low cost.
