This standard concrete beam bridge crosses 7th Street in downtown Bismarck.
Built in 1979, the bridge was only the third grade separation project in the small capitol city of Bismarck.
Consisting of an I-Beam span and a small slab approach, the bridge is set onto concrete substructures, and covered by a concrete facade.
Overall, the bridge remains in good condition because of its newer age.

The author has ranked this bridge as being minimally significant, due to the newer age and common design.
The photo above is an overview. The bridge can be accessed from the road it crosses.
