This small stone arch bridge crosses a small drainage stream near the Riverfront Drive Overpass.
Built in 1886, this bridge uses a standardized stone arch design. The bridge has a large headwall on the south face.
Arches like these are common for crossing small streams. Although more expensive than a timber bridge, these structures oftentimes remain in near mint condition over 100 years after construction.
Overall, this bridge appears to be in good condition.

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