High Quality Content by WIKIPEDIA articles! Interstate 84 (I-84) is an Interstate Highway in the Western United States that runs from Portland, Oregon, to a junction with Interstate 80 near Echo, Utah. The highway is a fork of I-80 to serve the Pacific Northwest, and was originally numbered Interstate 80N. The highway was signed with the I-84 designation in 1980, when a 1977 change in guidelines took effect that discouraged highway numbers with directional suffixes. The renumbering resulted in two highways being numbered I-84, with the other residing in the Northeastern United States.
