Second Street–Gun River Bridge

The Second Street–Gun River Bridge was a bridge in Martin Township, Michigan, USA. It was demolished in 2012. The bridge was significant as a rare example of a bridge with a plaque stating that it had been built as a result of Michigan's Covert Act.[2] It was also one of the few remaining examples of a camelback highway bridge in Michigan.[3]

History

The bridge was built in 1926 as part of the Covert Act, which required the state, upon request of the appropriate locality, to construct all trunk-line roads. The Allegan County Road Commission hired Yost Brothers of Decatur, Indiana, to construct the bridge. The bridge is believed to have been based on a standard Michigan State Highway Department plan for a curved-chord concrete girder bridge.[4] It was listed on the National Register of Historic Places in 1999.[1] The bridge was demolished in 2012 as part of a road improvement project.[5][3]

Description

The Second Street–Gun River Bridge consisted of a single concrete through-girder span, 48 feet in length. The substructure contained concrete abutments with both T-shaped and flared. The bridge's concrete girders had curved tops with six cast window-like recesses. The deck was 29.3 feet wide, with a 22 feet wide roadway covered with blacktop. The corner posts had squared caps and bases, with four curved concrete brackets at the corner of each girder.[2]
