Interstate 84

Interstate 84 is divided into two parts. The western Interstate 84 begins at Interstate 5 in Portland, Oregon, and goes east through Hood River, The Dalles, Pendleton, and Ontario before entering Idaho, where it serves Caldwell, Boise, and Twin Falls. Finally, the western Interstate 84 enters Utah, where it lasts just 119 miles and goes through Brigham City and Ogden before terminating at Interstate 80 at Echo Junction. The western Interstate 84 was originally Interstate 80N.

The eastern Interstate 84 is not nearly as long (232 miles compared to 770 for the western Interstate 84), but serves more populated areas, including Scranton, Newburgh, Danbury, and Hartford. It travels through mountainous terrain throughout its route. Between current Interstate 384 in Hartford and Interstate 90 in Sturbridge, Massachusetts, Interstate 84 was originally Interstate 86. This was because Interstate 84 was planned to continue east along the U.S. 6 corridor to Providence, Rhode Island. When those plans fell through, Interstate 84 was then signed along the former Interstate 86.
