context_page_description: Interstate 82 is an Interstate Highway in the Pacific Northwest region of the United States that travels through parts of Washington and Oregon. It runs 144 miles from its northwestern terminus at I-90 in Ellensburg, Washington, to its southeastern terminus at I-84 in Hermiston, Oregon. The highway passes through Yakima and the Tri-Cities, and is also part of the link between Seattle and Boise, Idaho. I-82 travels concurrently with U.S. Route 97 between Ellensburg and Union Gap; US 12 from Yakima to the Tri-Cities; and US 395 from Kennewick and Umatilla, Oregon.
  I-82 primarily serves the Yakima Valley agricultural region, following the Yakima and Columbia rivers southeastward to the Tri-Cities. The highway enters the valley from the north by crossing the Manastash Ridge, which separates Yakima from the Kittitas Valley. I-82 bypasses the Tri-Cities by traveling southwest around Richland and Kennewick and then turns south to cross the Columbia River on the Umatilla Bridge. Its only auxiliary route, I-182, connects the highway to Richland and Pasco in the Tri-Cities.
context_section_description: I-82 begins southeast of Ellensburg, Washington, at a trumpet interchange with I-90, the state's major east–west freeway. I-82 travels southward in a concurrency with US 97, which continues northwest along I-90 around Ellensburg and intersects with SR 821 at Thrall on the southern edge of the Kittitas Valley. The freeway climbs the Manastash Ridge, traveling southeastward around 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 the plateau to the Columbia River Gorge. The freeway reaches its highest point at Vanderbilt Gap, which is 2,672 feet (814 m) above sea level and only 300 feet (91 m) lower than Snoqualmie Pass on I-90. From the gap, the highway crosses into Yakima County and turns southwestward as it begins its descent from the ridge.
  Just north of Selah, I-82 crosses the Fred G. Redmon Bridge, a 325 feet (99 m)-high, twinned arch bridge that spans Selah Creek. 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 to new bridges in St. Paul, Minnesota, and Franklin, Tennessee. Southwest of the bridge, the freeway passes several farms and industrial buildings before reaching an interchange with the southern end of SR 821. I-82 continues on the eastern bank of the Yakima River to the east of Selah and intersects SR 823 in Selah Gap, a narrow canyon between two arms of the Yakima Ridge. The freeway, which runs parallel to a section of SR 823 in its median, crosses the Yakima and Naches rivers at their confluence and enters Yakima.
  On the southern side of the confluence, I-82 and US 97 intersect US 12, a major cross-state highway that uses White Pass to travel over the Cascade Mountains, and begins a concurrency with it. The three highways travel southward 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 dogbone–partial cloverleaf interchange at the Valley Mall. I-82 continues southward through Union Gap and splits from US 97 at the eponymous canyon, where it crosses the Yakima River with US 12.
  I-82 and US 12 travel southeastward in the shadow of the Rattlesnake Hills and along the north side of the Yakima River, opposite from US 97 and the BNSF Railway's Yakima Valley Subdivision on the Yakama Indian Reservation. The freeway follows the Central Washington Railroad and intersects several roads connecting to cities on the southern side of the river, including Wapato and Toppenish, the latter of which is connected via an interchange with SR 22 near Buena. This section of the highway also passes through the Yakima Valley agricultural region, which includes Rattlesnake Hills AVA and Yakima Valley AVA—major areas for wine and hops production, along with other crops. I-82 travels along the southern 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. Past Zillah, the freeway intersects SR 223 in Granger and SR 241 southeast of Sunnyside, bypassing both towns. I-82 continues southeastward through Grandview and toward Prosser at the edge of the Tri-Cities metropolitan area in Benton County.
