Learn about Michigan's Unique Concrete Camelback Bridges

This is the least-deteriorated examples of the curved-chord through girder bridge in St. Clair county in terms of structural integrity. The concrete has not experienced much spalling, which is good. The structure is skewed quite noticeably. The bridge has State Reward Bridge plaques on it. The bridge was built in 1922, which makes it an early and well preserved example of its structure type.

There is no weight limit on this bridge, there are currently no plans to replace it! However, knowing St. Clair County this will not always be the case. It is important that this bridge not be demolished. The time to restore this bridge, perhaps by applying a protective concrete sealant, is now, before the bridge becomes deficient and costs to rehabilitate increase.

Information and Findings From Michigan Historic Bridge Inventory

Narrative Description

This is the oldest known surviving example of a standard Michigan State Highway Department concrete camelback bridge of 50 feet. Michigan's Department developed standard designs in the late 1910s as a way of producing inexpensive bridges for the State Trunkline System, and was a national leader in doing so. Richard Adler of Port Hope, Michigan, was the bridge contractor.
