This bridge is an example of the Wrought Iron Bridge Company earlier design for a large span Whipple truss. It has been rehabilitated for continued vehicular use at the expense of historic integrity and alteration. Floorbeams, pins, and other elements are not original. Many rivets were replaced with high strength bolts. An interesting feature of the rehabilitation was that it was galvanized instead of painted. The silver/grey color created by galvanization is not offensive, and indeed its lighter color helps bring the truss bridge details out. The bridge is rare as an example of a Whipple truss, and also the last remaining highway truss in Lake County, Ohio.
Information and Findings From Ohio's Historic Bridge Inventory
The bridge is a 1-span, 167'-long, double-intersection Pratt (Whipple) truss. It is composed of built-up compression members and eye-bar or rod tension members. There are lattice portals with builders plaques and a decorative shield displaying the date of construction.
Rehabilitated in 2006.
Summary of Significance
The 1881 double-intersection Pratt (Whipple) truss bridge is a technologically significant example of its type/design fabricated by the Wrought Iron Bridge Co., a prominent Ohio fabricator. It was sensitively rehabilitated in 2006. The eligible recommendation of the prior inventory remains appropriate.
There are at least 14 examples of the bridge type important to the development and maturation of the pin-connected thru truss bridge. They date from 1881 and concentrate in the 1880s. Even though there are more than 12 extant examples in Ohio, each built in the 1880s has high significance based on overall scarcity (everywhere but in Ohio) of the design. This is a major and technologically significant bridge type. The bridge has high significance.
