Interstate 82 (I-82) is an Interstate Highway in the Pacific Northwest region of the United States, traveling through parts of Washington and Oregon. It runs 144 miles (232 km) from Ellensburg, Washington, to Hermiston, Oregon, passing through Yakima, Washington, and the Tri-Cities area. The highway also functions as a connection between I-90 and I-84, which continue on to Seattle and Boise, Idaho, respectively.

I-82 travels concurrently to U.S. Route 97 (US 97) between Ellensburg and Union Gap, south of Yakima, and US 12 from Yakima to the Tri-Cities. It has one auxiliary route, I-182, which connects the highway to Richland and Pasco in the Tri-Cities. I-82 primarily serves the Yakima Valley region, following the Yakima and Columbia rivers southeastward to the Tri-Cities. It crosses the Columbia River on the Umatilla Bridge and runs southwesterly through Umatilla County, Oregon, terminating at I-84 southwest of Hermiston.

The corridor was originally used by several state and national highways, including the Inland Empire Highway and US 410, that were built in the early 20th century. I-82 was created in 1958 by the federal government to serve military facilities in the region, replacing an earlier designation for what is now I-84. Several disputes over the routing of the highway, particularly in the Tri-Cities area, delayed the start of construction for most of the highway until 1969. Its last segment was completed in 1988, marking the final part of the Interstate system in Oregon. Plans to extend I-82 further south through eastern Oregon and towards California were proposed in the late 1990s, but rejected for further consideration.[why?]

Interstate 82 travels 143.5 miles (231 km)[1] through a part of the Inland Northwest region in a generally northwest–southeast direction along the Yakima and Columbia rivers.[4] It is part of the link between Seattle, Washington, and the inland West, which includes Boise, Idaho, and Salt Lake City, Utah.[5][6] As a component of the Interstate Highway System, I-82 is also designated as an important national highway under the National Highway System.[7][8] It is also listed as a Highway of Statewide Significance by the Washington state government.[9]

I-82 is maintained by the Washington State Department of Transportation (WSDOT) and Oregon Department of Transportation (ODOT) within their respective states. Both agencies conduct annual surveys of traffic on segments of the freeway, expressed in terms of average annual daily traffic (AADT), a measure of traffic volume for any average day of the year. The heaviest and least traveled sections of I-82 are both located in Washington; the busiest section, in downtown Yakima near State Route 24 (SR 24), carried a daily average of 52,000 vehicles in 2016; and the least busiest, the terminus at I-90 near Ellensburg, carried 9,100 vehicles.[10] In 2016, ODOT measured 21,700 vehicles at the Umatilla Bridge and 13,700 at Powerline Road near Hermiston, marking the busiest and least busiest sections of the highway within Oregon.[11]

Yakima Valley[edit]

I-82 begins southeast of Ellensburg, Washington, at a trumpet interchange with I-90, the state's major east–west freeway.[12] I-82 travels south in a concurrency with US 97, which continues northwest along I-90 around Ellensburg, and intersects State Route 821 (SR 821) at Thrall on the south edge of the Kittitas Valley.[4] The freeway ascends the Manastash Ridge, traveling southeast around the Yakima River Canyon, where SR 821 runs as a meandering scenic byway. Here, I-82 also forms the western edge of the Yakima Firing Range, a military training and exercise facility that stretches across to the Columbia River Gorge. The freeway reaches its highest point at Vanderbilt Gap, 2,672 feet (814 m) above sea level and only 300 feet (91 m) lower than Snoqualmie Pass on I-90, and begins its southwesterly descent into Yakima County.[13][14]

Just north of Selah, I-82 cross 325 feet (99 m) above Selah Creek on the Fred G. Redmon Bridge, a twinned arch bridge. At the time of its opening in 1971, the Redmon Bridge was the longest concrete arch bridge in North America, at 1,337 feet (408 m), but lost its record in 1993 after being surpassed by new bridges in St. Paul, Minnesota, and Franklin, Tennessee.[15] Southwest of the bridge, the freeway passes several farms and industrial buildings before reaching an interchange with SR 821 and SR 823. I-82 continues on the east bank of the Yakima River to the east of Selah and intersects SR 823 again in the Selah Gap, a narrow canyon between two arms of the Yakima Ridge.[16] The freeway, paralleled by a local street in its median, crosses the Yakima and Naches rivers at their confluence and enters Yakima.[13][17]

On the south side of the confluence, I-82 and US 97 intersect US 12, a major cross-state highway that uses White Pass to cross the Cascade Mountains, and begins a concurrency.[4] The three highways travel south along the Yakima River, veering east of downtown Yakima and its inner neighborhoods. The freeway passes through several urban interchanges, including the western terminus of SR 24 at Nob Hill Boulevard and a hybrid dogbonepartial cloverleaf interchange at the Valley Mall.[18] I-82 continues south through Union Gap and splits from US 97 at the eponymous canyon, where it crosses the Yakima River with US 12.[13][16]

I-82 and US 12 travel southeast under the Rattlesnake Hills and along the north side of the Yakima River, which marks the eastern boundary of the Yakama Indian Reservation, opposite US 97 and the BNSF railroad. The freeway intersects several roads connecting to cities on the south side of the river, including Wapato and Toppenish, the latter connected via an interchange with SR 22 near Buena.[4] This section of the highway also passes through the Yakima Valley agricultural region, which includes two major areas for wine production (Rattlesnake Hills AVA and Yakima Valley AVA) and the cultivation of hops and other crops.[19] I-82 travels along the south edge of Zillah and passes the historic Teapot Dome Service Station, a gas station and piece of political and novelty architecture that became a roadside attraction.[20][21] Past Zillah, the freeway intersects SR 223 in Granger and SR 241 southeast of Sunnyside before making a southeasterly turn through Grandview and towards Prosser in Benton County, part of the Tri-Cities metropolitan area.[13]

Tri-Cities and Umatilla[edit]

I-82 and US 12 pass several wineries and tasting rooms in northern Prosser before crossing the Yakima River east of the city center. The freeway continues northeast on the south side of the Yakima River, running along the bottom of the Horse Heaven Hills. Near Chandler Butte, the highway turns southeasterly and intersects SR 224 and SR 225 on the south side of Benton City. I-82 continues east to an interchange with I-182, its sole auxiliary route, near West Richland; from here, I-182 travels concurrently with US 12 into Richland and Pasco, while I-82 bypasses the Tri-Cities to the southwest, staying south of Badger Mountain.[4] I-82 continues southeast along the edge of the Horse Heaven Hills to an interchange with US 395 south of Kennewick, where it forms another concurrency.[4][13]

I-82 and US 395 travel south and ascend the Horse Heaven Hills, coming to an intersection with SR 397, a recently-built highway which provides alternative points of access for Kennewick and Finley.[22] The freeway continues southwest along Bofer and Fourmile canyons, descending from the hills and passing irrigated farmland while approaching the Columbia River. Northeast of Plymouth, it intersects the eastern terminus of SR 14, a cross-state highway that follows the Columbia River west to Vancouver, and passes over railroad tracks that carry Amtrak's Empire Builder passenger trains.[4][13] I-82 and US 395 cross the Columbia River west of the McNary Dam on the Umatilla Bridge, which constitute a unique multiple cantilever, steel truss bridge carrying the eastbound lanes and a newer concrete segmental bridge that carries the westbound lanes and a multi-use trail for bicyclists and pedestrians.[23][24][25]

After crossing into Oregon, the freeway enters Umatilla and intersects US 730, which becomes briefly concurrent with US 395 after it splits from I-82. I-82, designated as the unsigned McNary Highway No. 70 under Oregon's named highway system,[3] continues southwest across the Umatilla River around central Hermiston.[26] The freeway runs along the edge of the Umatilla Chemical Depot and terminates at an interchange with I-84 (concurrent with US 30) southwest of Hermiston;[13] I-84 and US 30 continue west along the Columbia River towards Portland and east to Pendleton and Boise, Idaho.[27]

History[edit]

The Fred G. Redmon Bridge carries I-82 over Selah Creek north of Selah.

As part of Washington's first connected state highway system, the Washington State Legislature designated the Inland Empire Highway between Ellensburg and Laurier in 1913.[28] The State Highway Board selected a route that would connect the main cities of Eastern Washington and the Inland Empire, which were Ellensburg, Yakima, the Tri Cities, Colfax, and Spokane.[29][30] In 1923, by which time the entire road had been improved,[31] the highway became State Road 3 (Primary State Highway 3 and Primary State Highway 3 WA after 1937), but retained its name.[32] By that time, most of the route of Interstate 82 became parts of US 410, US 97, and US 395, all three were established in 1926.[33][34][35]

In the initial plans for the Interstate Highway System, the Interstate 82 designation was used for what is today signed Interstate 84 from Utah to Washington. However by the time the plan was finalized in 1956, the Utah to Washington freeway was designated Interstate 80N and the modern incarnation of I-82 was developed. At that time I-82 fit the numbering scheme for interstate highways; however, I-80N has since been re-designated I-84, causing the I-82 to be out of sequence for interstate highways.[36][37]

Even though I-82 was designated in 1956, construction did not start until March 1969,[38] and the last section of within Washington opened in 1987.[39] Legally, the Washington section of I-82 is defined at Washington Revised Code § 47.17.135.[40] Several projects are currently ongoing and have been completed in the recent years on I-82.[41]

The Ellensburg–Yakima section of I-82 was graded and constructed from 1969 to 1971.[42][43][38]

I-82 was meant to go from Tacoma, across Naches Pass, and then southeast into Yakima and the Tri-Cities.[not in citation given] The proposal was quickly denied and later resurfaced as the SR 168 Proposal.[44]

The original plans for the included two options. One was the current route (which was opposed by the Tri-Cities), and another had I-82 go from Prosser into Richland and Pasco, and then southeast to Wallula and then end at I-80N (present-day I-84) in Pendleton. The first option was chosen, but the Tri-Cities needed access, so the Federal Highway Administration created Interstate 182, which would serve as a connector from I-82 to the Tri-Cities.[45][46] [47]

When I-80N was renumbered I-84 in 1980, I-82's designation became a violation of the Interstate system's numbering rules, as it was now located north of I-84. The reason for the renumbering was a change in guidelines published by the American Association of State Highway and Transportation Officials that advised renumbering suffixed routes.[36][37] In 1999, a plan surfaced to extend I-82 further south in Oregon. Three major routes were proposed including the Madras Route, from Umatilla through Heppner, Condon, Fossil, and Antelope to Madras, where I-82 would replace US 97 south through Bend to the California border, the Prineville route, from Umatilla through Heppner, Hardman, Spray, Prineville, and Powell Butte to US 97 near Bend, then continue south to the border, and the US 395 route, from Umatilla through John Day, Burns, and Lakeview, presumably to the California border and beyond.[48][49]
