Interstate 84

Interstate 84 is the designation of two interstate highways in the United States.

The western Interstate 84 runs from an intersection with Interstate 5 at Portland, Oregon to an intersection with Interstate 80 at Echo, Utah -- roughly the same route as the Oregon Trail. Starting in Portland, the interstate runs through the Columbia River Gorge and alongside the Columbia River Highway to The Dalles, then continues along the Columbia River to Boardman at which point it veers off in a southeasterly direction toward Ontario at the Idaho border.

Notes

Connecting these routes is easy, I-84 "joins" I-80 in Utah, and then joins I-81 in Pennsylvania.

Originally the part of I-84 east of Hartford was numbered I-86 and I-84 was going to go to Providence. Only I-384 (and some memories of cryptic roadsigns saying first that I-84 was to become I-86 for no apparent reason, and then they said I-86 is now I-84) remains of this project.

The western Interstate 84 was originally numbered Interstate 80N. It was given its new designation in 1980.
