[3] 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 the Yost Brothers of Decatur, Indiana, to construct the bridge.
[5][3] 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.
