First constructed in 1885, the Tanners Falls Bridge is composed of two pin-connected Pratt pony trusses and a riveted Warren pony truss. The bridge has three spans, totaling 128'6" in length, and is 14' wide. The two eastern spans were built in 1885 by the Morse Bridge Company of Youngstown, Ohio. Both are Pratt pony trusses and measure 46' and 42' in length, respectively. The western span was replaced by a Warren pony truss in 1915 and measures 40'6" in length.  The structure is located in Dyberry Township, Wayne County, where it carried Tanners Falls Road (SR 40170) over the West Branch of Dyberry Creek until it was closed to vehicular traffic in 2007. The bridge is eligible for listing in the National Register of Historic Places.

Character-defining features of the bridge include the truss form (Pratt and Warren Pony), method of truss member end connection (pinned and riveted), structural members to include the top and bottom chords, vertical and diagonal members, placement of the floorbeams above the lower chord (Pratt trusses) and builder plaques (Warren truss).
