Interstate 84 (I-84) in the U.S. state of Idaho is a major Interstate Highway that traverses the state from the Oregon state line in the northwest to Utah state line in the southeast. It primarily follows the Snake River across a plain that includes the cities of Boise, Mountain Home, and Twin Falls. The highway is one of the busiest in Idaho and is designated as the Vietnam Veterans Memorial Highway.
I-84 runs for 276 miles (444 km) within Idaho, beginning near Ontario, Oregon, and traveling concurrent with several U.S. routes through the Boise metropolitan area and Mountain Home towards Twin Falls. I-84 splits away from US 30 and the Snake River at a junction with I-86 near Declo, where it turns southeast to cross the Sublett Range into northern Utah. The highway has an auxiliary route, I-184, which serves downtown Boise.
