I-80N was generally built along the corridor of U.S. Route 30
and U.S. Route 30S
; the U.S. Route 30S designation was decommissioned in the 1970s after the freeway replacement was mostly complete. 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.

East of Pendleton
, I-84 climbs Emigrant Hill
, a 6% grade, into the Blue Mountains
. This grade is known for the fact that the westbound lanes switchback twice on its descent into Pendleton. Eastbound lanes feature what are the tightest curves allowed on the Interstate Highway system, even though those curves are on the uphill (eastbound) direction. This grade is also well known due to the fact that it features such a great distance between eastbound and westbound lanes, nearly 2 miles (3.2 km) between the opposite directions of travel at some points. The road summits at 4193 feet (1278 m) above sea level before descending to the Grand Ronde River and La Grande
. It passes by North Powder
and Baker City
and through the Burnt River
canyon. Around Huntington
, it crosses into the Mountain Time Zone
then briefly follows the Snake River (Brownlee Reservoir
), then continues to Ontario to cross the Snake River into Idaho.
at Ontario, Oregon
. From there, it continues on to the major cities of the Treasure Valley
, or Boise metropolitan area
, including Caldwell
, Nampa
, Meridian
, and Boise
(where I-184
connects travelers to downtown). From Boise, I-84 continues southeast towards Twin Falls
, after passing near several small cities (Mountain Home
, Glenns Ferry
, and Jerome
).
Just east of Jerome, I-84 passes within 5 miles (8 km) of Twin Falls, but does not cross the Snake River Canyon
or into Twin Falls County
. Access to Twin Falls is afforded by an intersection with US 93
at Exit 173; US 93 southbound crosses the Snake River via the Perrine Bridge
.
After Twin Falls, I-84 continues through Burley
and Heyburn
. Approximately 7 miles (11 km) east of Declo
in rural Cassia County
, I-84 meets I-86. I-84 heads southeast towards Utah and I-86
heads east, then northeast to American Falls
and Pocatello
, following the Oregon Trail
.
in Box Elder County
. It proceeds southeast towards Tremonton
where I-84 joins I-15
.
Just south, at Corinne, Utah
, I-84 joins the route of the First Transcontinental Railroad
which the highway follows to its terminus. I-15/I-84 pass to the west of Ogden
where I-84 separates from I-15 and follows the Weber River
. As the freeway passes through Weber Canyon
it also passes through several small farming communities, including Morgan
, where the Browning Arms Company
headquarters can be seen from the freeway. Also visible in the canyon is Devil's Slide
, an unusual rock formation just off the freeway. Farther up the canyon is the Thousand Mile Tree
, planted by Union Pacific Railroad
workers to mark 1000 miles (1,609.3 km) from the railroad's origin in Omaha, Nebraska
. The freeway ends at Echo
, a near ghost town that before served as a stopover for the railroad, at a junction with Interstate 80
. Also near the junction is Echo Reservoir and Echo Dam.
The Utah sections of I-84 not concurrent with Interstate 15
are defined at Utah Code Annotated § 72-4-114(4).
American Association of State Highway and Transportation Officials
established guidelines recommending that "suffixed" highways, such as I-80N, be renumbered. In 1977, Idaho officials recommended that I-80N be renumbered to I-84. The motion was seconded by officials in Utah, but opposed by Oregon and Washington. The motion passed on July 7, 1977, and the states were given until July 1, 1980 to implement a co-ordinated renumbering strategy.
After renumbering, I-84 violated the Interstate Highway Numbering Convention by being south of I-82. The Portland segment of then-I-80N was proposed to run on the Mount Hood Freeway. Plans for this were officially dropped in 1978 after a successful freeway revolt.
