Located north of Auburn, this bridge crosses Xavier Avenue.
Built in 1915, the bridge features a single concrete encased I-Beam span, approached by a single concrete slab span on the east. The entire bridge sits on concrete substructures.
Overall, it appears that the bridge is in fair condition, with some spalling on the bridge. The bridge has been rehabilitated with new concrete added to the spans. The concrete encased beam type bridge appears to have been common on this line, and may have been favored due to the durability.

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