The Old US 41–Backwater Creek Bridge is a bridge located on an abandoned section of US Highway 41 (US 41) over Backwater Creek in Baraga Township, Michigan. It was listed on the National Register of Historic Places in 1999.〔 ==History== In 1913, the state of Michigan authorized the construction of trunkline roads through the state. A main trunkline route through Baraga County was designated, extending from Michigamme to Chassell. By 1915, the trunkline had been completed, and the Baraga County Road Commission spent the remainder of the decade slowly improving the route, regrading segments and replacing some bridges.〔 One of the improvements along the route was the construction of a bridge across the end of Keweenaw Bay, south of Baraga.〔 The Michigan State Highway Department designed a long-span pony truss bridge for the crossing, designated State Trunk Line Bridge No. 86. In 1917, the department awarded contracts for the construction of the bridge: Smith-Sparks Construction Company was awarded $5,414.20 to fabricate the concrete substructure, and the Northwestern Bridge and Iron Company fabricated and installed the truss for $4,536.00. The structure was completed in 1918.〔 In 1926, the trunkline road was incorporated into US 41. Traffic along the route increased, and eventually a replacement bridge was built nearby.〔 The original bridge remains, in essentially unaltered condition, and is now a privately owned structure.〔
