This small standard through girder bridge crossed Marble Creek just west of Ladora.
Built in 1907, the bridge clearly had received updates to the substructures in the last 30 years.
Consisting of a single through girder span, the entire bridge sat on concrete substructures. It would appear modifications to these occurred in the late 20th Century, and included encasing an older abutment in concrete.
Overall, the bridge remains in good condition. Like many structures along this route, the bridge had been rehabilitated into good condition.

The author has ranked this bridge as being locally significant, due to the common design of the bridge. The bridge was replaced the morning of November 18th, 2021.
The photo above is an overview. The bridge can be accessed from US-6.
