Located east of Rubio, this concrete deck girder bridge crosses Dogwood Avenue.
Built in 1909, the bridge features five spans of concrete deck girder, set onto concrete substructures.
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, and rehabilitation work was done on the bridge sometime around 1990.

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