Learn about Michigan's Unique Concrete Camelback Bridges

This bridge survived a brutal attack of water and debris caused by the breaking of dams on Dead River during the spring of 2003. With a much lower clearance than its ugly replacement, the water pounded into this bridge, testing its strength. The bridge came out hardly scratched. The ground around the bridge was washed out completely. This is a curved-chord though girder bridge, aka concrete camelback, with unique end posts that are not on any other concrete camelback remaining in Michigan. It does not have any plaques, but the National Bridge Inventory reported a 1931 construction date. If this is accurate, it would have been one of the last concrete camelback bridges built in the state.

Following the 2003 flood, this bridge's approaching roadways were rebuilt, and the bridge remains open to non-vehicular traffic. It is one of the few concrete camelback bridges that appears to be completely free from risk of demolition.
