Sturgeon Bay Bridge (aka:Michigan Street bridge)
The Sturgeon Bay bridge spans the Sturgeon Bay Ship Canal in the central business district of Sturgeon Bay in scenic Door County. In engineering terms, the 1,420-foot bridge is comprised of a scherzer-type rolling-lift bascule "movable" span and 12 concrete and steel truss approach spans. The Michigan Street bridge was built in 1930 and was the largest bridge built in Wisconsin at the time.
The bridge is nationaly significant because of its engineering and locally because of the central location in the city It is on the National Register of Historic Places.
The bridge rehabilitation will replace much of the operating machinery while preserving the historical integrity of the operating system. The estimated cost of rehabilitation is $13 million.
