Located between Rubio and Richland, this bridge crosses Richland Creek on a deck girder bridge.
Built in 1909, the bridge features a pair of deck plate girder spans, approached by concrete deck girder spans on either side.
During the upgrading of this line during 1909 and 1910, several unique designs were used, from double layered arches to cutting edge concrete bridges.
A majority of the concrete bridges were various slabs and concrete girders. The concrete deck girders never really caught on outside of select spans on Milwaukee Road mainlines, while slabs became the new standard.
Overall, the bridge appears to be in fair condition. Less than normal deterioration was noted on the bridge.

The author has ranked this bridge as being locally significant, due to the common design.
