INTERSTATE 82

:''This article is about the highway. For the video game, see Interstate '82.''
'Interstate 82' (abbreviated 'I-82') is an interstate highway in the northwestern United States, completed in the late 1980s. Currently just under 144 miles (231 km) in length, its western terminus is at Interstate 90 in Ellensburg, Washington, and its eastern terminus is at Interstate 84, just southwest of Hermiston, Oregon.

Route description

I-82 serves two major purposes:

★ Long haul/long trip

★
★ A link between Seattle and inland western cities such Boise, Salt Lake City, and Denver.

★ Short trip traffic accounts for the vast majority of the actual traffic:

★
★ I-82 serves at a local connector between cities along the Yakima River.

★
★ Between Ellensburg and Yakima

★
★ Between Yakima and lower Yakima Valley cities such as Toppenish and Sunnyside

★
★ Continuing on to the Tri-Cities area (Kennewick, Richland, and Pasco) and the Hanford Nuclear Reservation

I-82 crosses Selah Creek, just north of Selah over the Fred G. Redmon Bridge. At the time it was constructed in 1971, the twin-arch bridge was the longest concrete arch bridge in North America. The bridge is 1337 feet long (407 m), and rises 325 feet (99 m) above the canyon floor. The arch spans (excluding approach spans) are 549 feet long (167 m).
In 1999, a plan surfaced to extend I-82 further south in Oregon. Three major routes were proposed:

★ 'Madras Route:' "From Umatilla through Heppner, Condon, Fossil, and Antelope to Madras, where the interstate would replace US-97 south through Bend to the California border."

★ 'Prineville Route:' "From Umatilla through Heppner, Hardman, Spray, Prineville, and Powell Butte to US-97 near Bend, then continue south to the border."

★ 'Highway 395 Route:' "From Umatilla through John Day, Burns, and Lakeview," presumably to the California border and beyond. [1]
If the highway is extended, it will likely be renumbered to a route number that reflects its north-south status (an odd number, greater than 5 and less than 15), such as Interstate 7 or Interstate 9 (the number not chosen for the upgrade of California State Highway 99). Another idea has surfaced to renumber I-82 between the Tri-Cities and Ellensburg as a 3-digit extension of Interstate 90 and to designate U.S. Highway 395 as part of Interstate 7 or 9 if the Oregon extension is built.
I-82's designation is a violation of the Interstate system's numbering rules, as it is located north of I-84. The original designation for I-84 was I-80N, but was renumbered in 1980 as part of a mandate to eliminate suffixed routes. In addition, the planned western terminus for I-82 was originally Tacoma (instead of Ellensburg, with the route proceeding west from Yakima (instead of north) along the US-12 and SR-410 grades, up the Naches River over Naches Pass (currently proposed as SR-168) north of Mt. Rainier National Park.
The brief section (11 mile, 17 km) of I-82 in Oregon is designated the 'McNary Highway', as it passes just below the McNary Dam on the Columbia River.
The route of the Washington section of I-82 is defined in Washington Revised Code § 47.17.135.[2]
