Interstate 84 is a designation applied to two different expressways in the United States. The western iteration of Interstate 84 runs from Portland, Oregon, to a point just east of Salt Lake City in northern Utah. For the other Interstate 84 farther east, from northeastern Pennsylvania into New England, click here. The western Interstate 84 has its western end situated in Portland, Oregon, at an interchange with Interstate 5, just east of downtown. Interstate 84 continues east along the northern end of Oregon near the Columbia River. In north-central Oregon, around Pendleton, Interstate 84 curves southeastward to exit the state at the middle of its eastern border. That egress out of Oregon occurs at Ontario, Oregon, entering Idaho. Interstate 84 is the longest, most important east-west highway for accessing populated areas of Idaho, as it passes through the Snake River Valley, including interchanges to Boise and Twin Falls. Interstate 84 deviates southeasterly from the Snake River Valley about two-thirds across the width of Idaho, sending Interstate 86 along the Snake River in its stead. The new southeastern pathing of Interstate 84 soon takes it across the state border into Utah, where it joins Interstate 15 south to Ogden. At Ogden, Interstate 84 splits from Interstate 15 to head east into the mountains for another forty miles. Those forty miles come to a close and Interstate 84 comes to a close at Interstate 80, at the small town of Echo. Most traffic reaching the eastern end of Interstate 84 continues onto Interstate 80 eastbound, toward Cheyenne, Wyoming and the middle and eastern parts of the country.
My photo for Interstate 84's western edition comes from Arlington, Oregon. Access from Interstate 84 to Arlington and Oregon Highway 19 is provided by a pair of nearby partial interchanges; a western one provides access to/from the west, and the eastern one provides access to/from the east. The sign assembly depicted faces west, just short of the eastern partial interchange. Eastbound traffic on the side road knows, by looking at this sign, that Oregon Highway 19 starts off going to the south from here, whereas continuing straight eastward will put them on an onramp to Interstate 84 eastbound. Interstate 84 also carries US Route 30 along the relevant stretch here passing Arlington, like it does through most of its time in Oregon. The photo was taken along the drive to the Pacific Ocean at Astoria, Oregon, in August, 2018. Back to the nationwide main page. Back to the home page.
