Built in 1896, this standard deck girder bridge crosses Baraboo Street in Merrimac.
Consisting of a single span, the bridge features a pair of parallel spans, arranged in a 4-beam pattern. This style of construction is typical of 1890s bridges, specifically short spans. The bridge rests on stone substructures.
Overall, the bridge appears to be in good condition.
The author has ranked this bridge as being locally significant, due to the common design.
The photo above is an overview. The bridge can be accessed from the road it crosses.
