The historic Bergstresser/Dietz Bridge, the last remaining covered bridge in Franklin County, Ohio, is located within the city limits of Canal Winchester, Ohio in southeastern Franklin County. The wooden bridge crosses Little Walnut Creek, which is a tributary of the Scioto River. The Bergstresser Bridge was built in 1887 by the Columbus Bridge Company at a cost of $2,690. The Bergstresser Bridge is a well-built, sturdy structure, an outstanding example of late 19th-century engineering skills. It is the last original covered bridge in Franklin County and one of only 6 examples of the Partridge truss in existence today. The Franklin County Engineering Department keeps this bridge in excellent condition and has placed historical signs over each portal.
