 One bridge still in use crosses the Sturgeon River in Baraga County , known locally as the Canyon Falls Bridge . The structure was completed in 1948 as a steel arch bridge to span the river near the falls as part of a reconstruction project of US 41 between Ishpeming and L 'Anse . The crossing has a main span of 128 feet ( 39 m ) flanked by two 52 @-@ foot ( 16 m ) approach spans .
