23 Mile Road–Kalamazoo River Bridge : ウィキペディア英語版 | 23 Mile Road–Kalamazoo River Bridge }} The 23 Mile Road–Kalamazoo River Bridge is a curved-chord through-girder bridge in Marengo Township, Michigan, that carries 23 Mile Road over the Kalamazoo River. Built in 1922, it is listed on the National Register of Historic Places. ==History== Prior to construction of the concrete structure, the river was spanned by another bridge at this location, presumably of a steel truss design. The new bridge was planned in January 1922 by the Michigan State Highway Department. Calhoun County subsequently built the structure as a State Reward Bridge. Mead Brothers of Battle Creek served as contractor in dismantling the previous span and building the new bridge. Construction cost $10,353.〔 The bridge was listed on the National Register of Historic Places on December 22, 1999.〔 It was eligible as one of the oldest examples of its design and for its well-preserved state.〔〔 The 12 Mile Road–Kalamazoo River Bridge, also in Calhoun County, was added the same day.
