Idaho Interstate Highways

Idaho's Interstate Highways connect its major cities and facilitate travel between Idaho and its neighboring states.  I-15 traverses eastern Idaho from north to south, between Montana and Utah; I-84 runs from western Idaho, through Boise, to southeastern Idaho.  I-86 connects I-84 with I-86 near Pocatello.  I-90 traverses northern Idaho from east to west, from the Montana border to the Washington border.  I-184 is a short feeder highway that links downtown Boise with I-84.

Idaho Scenic Routes

One of the best ways to view Idaho's scenic heartland is via a road trip north from Boise to the border of Montana.  Also known as the Payette River Scenic Byway, Route 55 travels through the Cascade Reservoir and the quaint mountain town of McCall before merging into Route 95 North.  Just past the town of Spalding, Route 12 takes travelers into Lolo Pass which is perched at an elevation of 5,233 feet, offering stunning views in all directions.  More information about scenic roads in Idaho is available on this Idaho Scenic Byways page.
