Interstate 84 Idaho Descriptions

I-84 enters Idaho at a crossing of the Snake River just east of Ontario, Oregon. From there, it continues on to the major cities of the Boise metropolitan area, including Caldwell, Nampa, Meridian, and Boise (where I-184 connects travelers to downtown). From Boise, I-84 continues on towards Twin Falls after passing near several small towns (such as Mountain Home, Glenns Ferry, and Jerome).

Just east of Jerome I-84 passes within 5 miles (8 kilometers) of Twin Falls, but does not cross the Snake River Canyon or into Twin Falls County. Access to Twin Falls is afforded by an intersection with US 93.

After Twin Falls, I-84 continues through Burley and Heyburn. At the intersection with I-86, approximately 7 miles (11.3 kilometers) east of Declo in rural Cassia County, I-84 veers southeast and heads toward Utah.
