Interstate 84 enters the state from Idaho at Curlew Valley in Box Elder County. Traveling eastward, the freeway runs between the Hansel and North Hansel Mountains to Rattlesnake Pass and Blue Creek Valley. The rural route encircles the Point Lookout Mountains to the merge with Interstate 15 at Tremonton.
Interstate 80N was complete across Utah by 1974 with the exception of a 9.8 mile link between Blue Creek Summit and Tremonton in Box Elder County. That section was scheduled for 1983,3 but work on the three year project did not commence until 1983. The $21 million project finally opened to traffic following a dedication ceremony held on September 25, 1986.4
