Interstate 84 marker

Interstate 84 (I-84) in the U.S. state of Oregon, also known as the Vietnam Veterans Memorial Highway, travels east–west, following the Columbia River and the rough path of the old Oregon Trail from Portland east to Idaho. For this reason, it is also known as most of the Columbia River Highway No. 2 and all of the Old Oregon Trail Highway No. 6 (see Oregon highways and routes). It also follows along or near U.S. Route 30. The entire highway carried the designation Interstate 80N (I-80N, or Interstate 80 North) until 1980, when this was changed to I-84.

Interstate 84 begins in Portland, Oregon where it connects with Interstate 5 on the east side of the Willamette River. It continues east, crossing Interstate 205, before curving to the north to join the Columbia River. It continues along the river, passing Interstate 82 in Hermiston, and U.S. Route 395 in Pendleton. It then curves to the south, until it gets to the Idaho border. It continues into Idaho.
