Overview
The Idaho Transportation Department is evaluating State Highway 75 (SH-75) between Torrey’s Hole River Access and Slate Creek in Custer County. Part of the evaluation process will identify potential improvements. The project is located about 22 miles east of Stanley.
The Salmon River Canyon provides limited space for widening SH-75. ITD will work with the United States Forest Service (USFS), local residents and road users to identify needs and determine improvements
