This bridge was a typical example of a late 20s and early 30s steel stringer bridge. This particular bridge was also noted for a skew. The railings were a complex, decorative design that came standard with bridges during this time. These bridges had their outermost beams covered in concrete to make the bridge look uniform from the side. Bridges like this are a stark contrast to modern engineering for bridges, where no attractive design is considered for people driving across the bridge, let alone for those who happen to stop the car, and take a look at the bridge from the side. Certainly this bridge's replacement will offer nothing more to look at. The loss of this bridge is a serious blow to Sanilac County, where the local county road commission has managed to demolish nearly every bridge of value.
