Appears to be a rare example of William Rezner's design, and may have been built by his short-lived Ohio Bridge Company between 1870-1873.
May also have been built by the Wrought Iron Bridge Company using Rezner's design after they acquired the Ohio Bridge Co. in 1873.
Jim Cooper has researched Rezner and his connection to this bridge. I will update information as it becomes available.
