This bridge is a three span concrete arch bridge, with earth fill. The bridge has had its original guardrails removed, which greatly detracts from the aesthetic qualities of the structure. In fact, most people probably don't know that this bridge is so old it was only the 256th bridge ever built as a trunkline bridge. The original plaque, set into the new guardrails remains to tell the fact. The plaque also mentions Rapid Railway Co, so this bridge must have once carried some sort of railroad tracks across its deck as well when it was built. MDOT's site lists this bridge as the sixth largest surviving earth filled concrete arch bridge in the state, at a length of 241 feet. MDOT lists the construction date as 1920, although the plaque lists a date of 1919. The bridge does not have a weight limit and continues to carry heavy traffic, testifying to the strength of the structure. There is some deterioration to the arches that if left unchecked will eventually become a problem.
