This simple deck girder bridge crosses Interstate 80 near Dexter.
A common design, the bridge is a four span deck girder. It rests on concrete substructures.
The bridge was built as a standard Interstate Highway overpass.
Overall, the bridge remains in good condition. It will likely serve until a complete rebuild of I-80 takes place.

The author has ranked the bridge as being minimally significant, due to the common design of the bridge and newer age.
