This large through truss bridge crosses the Heart River in Mandan.
Originally built in 1960, the bridge replaced a similar bridge which was relocated to south of Mandan.
It is believed that this structure was built as a flood prevention project along the Heart River. Currently, it contains a large 8-panel, riveted Warren Through Truss. This span is approached by I-Beam spans on either side, and the whole bridge sits on concrete substructures.
Overall, the bridge remains in good condition. Little has changed since construction for this bridge.
The author has ranked this bridge as being locally significant, due to the lack of historic railroad truss bridges in North Dakota.
The photo above is an overview. The bridge can be accessed from a nearby neighborhood.
