Located near the small town of Carnarvon, this small concrete arch culvert crosses a field drainage near Quincy Avenue.
Built in 1899, the bridge features a single concrete arch culvert span, set onto concrete substructures. This type of arch culvert was standard for this route.
Overall, it appears that the bridge is in good condition. Only deterioration of the headwall was found on the bridge.

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