Michigan is home to a unique and well-preserved collection of historic bridges that extends well beyond its most famous bridge, the Mackinac Bridge. Michigan is the birthplace of standardized in-kind restoration procedures for metal truss bridges. Experts in Michigan developed revolutionary new rehabilitation and restoration techniques for longer-lasting repairs that also retain historic integrity. Calhoun County is home to the first park in the country dedicated to historic bridges. Michigan's concrete curved chord through girder bridges (concrete camelback bridges) are a unique attraction. Even Michigan's younger bridges from the 1950s and 1960s have character, with attractive railings (known as R4 railings) and other decorative details. Whether they are your destination, or something you simply drive over on the way to other destinations, take a moment to appreciate the beauty of Michigan's old bridges. Michigan is the original and top area of coverage for HistoricBridges.org. HistoricBridges.org is proud to list all non-covered bridges that were listed on MDOT's now defunct Historic Bridges webpage. Many low-significance bridges are also documented on HistoricBridges.org, providing a comprehensive overview of all old bridge designs in Michigan. Please refer to the Historic Significance Rating (HSR) in the listings to reference how noteworthy each bridge actually is. Bridges whose HSR rating has a 7 or higher represent the best of Michigan's historic bridges, and are ideal destinations for tourists. HistoricBridges.org does not list covered bridges, so please visit this website for a listing of those.
