Located along former US Highway 66, this bridge crosses the Mackinaw River near Lexington.
Built in 1924 to replace a lightweight deck truss bridge, this span features three deck girder spans, set onto concrete and steel tower substructures.
The previous bridge utilized pin connected deck truss spans, with a stone center pier. When the present bridge was built, the old stonework was removed.
This style of bridge was very common for railroads, as it was easy and cheap to construct. The bridge received a heavy rehabilitation in 2015.
Overall, the bridge appears to be in good condition. Fortunately, this bridge is one of the few spared complete replacement along this route.

The author has ranked the bridge as being locally significant, due to the common design.
The photo above is an overview. The author hopes to return to this location for better photos in the future.
