The Idaho Dept. of Transportation has selected Wadsworth Brothers Construction of Draper, Utah, to reconstruct the Slate Creek Bridge on State Road 75 over the Salmon River at milepost 213. The bridge is located approximately nine miles west of Clayton. Construction is slated to begin this month.

The new Slate Creek Bridge will be constructed 38 ft upstream, adjacent to the current bridge.

The original bridge was erected in 1938 and is vital to east/west travel between Stanley and Challis, Idaho. The bridge was showing signs of deterioration and was recommended for replacement.

The new Slate Creek Bridge will be constructed 38 ft upstream, adjacent to the current bridge. It will be a 450-ft-long, three-span structure with two piers located at the water’s edge during normal summer flows. The new bridge will be wider, and although it has a railing, motorists will still be able to see the river below.

Construction is anticipated to occur over a two-year period, with traffic continuing across the old bridge until the new one is completed. The entrance to Slate Creek Road will be moved and realigned accordingly.

Wadsworth Brothers Construction has completed a number of bridge projects throughout the Intermountain region, including: The Eccles Legacy Pedestrian Bridge at the University of Utah, the only cable-stay bridge in the state; The Hurricane Arch Bridge spanning the Virgin River near Hurricane, Utah; and The Lego Bridges Project on I-215 in Salt Lake City.

The company is currently fulfilling a $38.5-million contract for UDOT that will construct two 1,022-ft concrete segmental bridges over the Colorado River in Moab, Utah.
