Canyon Falls Bridge
The Canyon Falls Bridge is a bridge located on US Highway 41 (US 41) over the Sturgeon River in L'Anse Township, Michigan. It was listed on the National Register of Historic Places in 1999.〔
==History==
During 1947–48, the Michigan State Highway Department (MSHD) contracted for the construction of eleven different trunkline bridges in the Upper Peninsula. Five of these bridges were required because of reconstruction to US 41. The Canyon Falls Bridge was designated Bridge No. B2 of 7-4-5 C2 by the MSHD. The steel arch bridge was designed by MSHD engineers and constructed for $116,389.42, plus an additional $58,200 for structural steel. The bridge was completed in the middle of 1948, and has remained in use in essentially unaltered condition since.〔
This bridge is significant because the steel arch design is relatively rare in the state, due largely to the fact that few river crossings afforded the required vertical distance. The Canyon Falls Bridge is a visually striking construction, representing the Highway Department's focus on aesthetics.〔
