Truss was originally fabricated in 1909 as part of Bridge #Z-1154 (Des Moines River Bridge near Madrid, Iowa) and moved here 1917. 72' deck girder replaced a 75' deck girder in 1931. 72' foot span rebuilt from an 1887 through girder, and 75' span shipped to Tomah bridge shops to be reused elsewhere. Information comes from CMStP&P records at the South Dakota Historical Society and the Milwaukee Road Archives at the Milwaukee Central Library.
