Michigan was not known for building concrete bowstring through arch bridges, commonly known as rainbow arch bridges. The state never designed a standard plan for a rainbow arch, probably because they had been pushing the unique curved-chord through girder design. The engineer for Adrian at the time, Jack Lemon designed the bridge. The bridge is currently posted for a 19-33-33 weight limit.
Michigan bridge enthusiasts will likely immediate think of this as an unusual bridge, although bridge enthusiasts from other states and provinces, like Ontario, will recognize the structure type more readily.
The Merrick Street Bridge was rehabilitated, which was great news since it means that this bridge will not be going anywhere and will remain for residents and visitors in Adrian to enjoy. The renovations are very extensive. As one crosses the bridge, the only materials to be seen that are original is the arch itself. The deck has been replaced, as well as the verticals for the arch. The floor beams also were replaced, along with the railings. Fortunately, these replaced portions of the bridge were replicated very well. While the loss of original materials in unfortunate, and affects the historic integrity of the structure, the end result is that this historic bridge remains as an attractive landmark. As such, the outcome is still good, and given the poor condition of the bridge prior to rehabilitation, the methods used were likely the best solution at the time.
