TRANSPORTATION – Adds to existing law to provide for studies regarding efficient and safe highway linkages.

Idaho's S 1115 requires the Idaho Transportation Department to conduct studies on improving highway safety and efficiency along specific corridors, including State Highway 95, 55, and 16 from Boise to McCall and New Meadows, plus a potential bypass south of I-84 near Nampa and Boise. The bill authorizes the department to use existing studies, accept private donations to offset costs, and maintain public records of funding. It mandates a final report with recommendations by July 1, 2027, detailing findings on optimal routes and infrastructure needs. This bill directly affects transportation planning for communities along these highways and the state's infrastructure development process.
