Located near the small town of Carnarvon, this massive concrete arch bridge crosses the Wall Lake Inlet.
Built in 1911, the bridge features a trio of large concrete arch spans, set onto concrete substructures. This type of arch culvert was standard for this route, although this appears to be the only structure with more than one span.
Triple concrete arches are very uncommon on American railroads. They typically indicate that the waterway is large, or there is a strong potential for flooding.
Overall, it appears that the bridge is in good condition. Virtually no serious deterioration was found on the structure, but it appears that the bridge may have received an encasement.
The author has ranked this bridge as being moderately significant, due to the exceptionally large bridge.
