The Sturgeon Bay Bridge (known as the Michigan Street Bridge) is a historic bridge in Sturgeon Bay, Wisconsin, United States. The bridge was built in 1929 and opened July 4, 1931, with a grand parade where it was officially dedicated as a Door County Veterans Memorial which plaques at either end still reads "To honor those who gave of themselves, to their country, in times of need" as a gift by the State of Wisconsin. It was the only bridge linking the mainland to northern Door County after the train/toll bridge was discontinued. The Sturgeon Bay Bridge was listed on the National Register of Historic Places on January 17, 2008, for its unique upper rolling lift bascule and length. After a ten-year battle to save the bridge from demolition and replace in-kind, it was determined by the state to add a second bridge as a sister to meet safety standards. In September 2008, after the opening of a new, parallel, two-lane sister bridge was opened one block away at Oregon Street, the historic bridge was temporarily closed to allow for restoration work to commence. Federal safety standards required four-lane replacement in order to accommodate the heavy traffic loads and congestion caused by the bridge's 3,000 openings annually. The historic bridge and new bridge operate as one system. The historic bridge was reopened in the spring of 2011.
