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.

[edit] 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).

There are scenic overlooks at the Northern end on the upgrade leading out of the Kittitas County. Rest Areas are at Selah Creek adjacent to the Redmon bridge and at Prosser in the lower Yakima Valley.

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]

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]

[edit] Rest Areas and Weigh Stations

The Washington State Department of Transportation (WSDOT) maintains three rest areas along I-82. The rest areas are located in two localities. One locality has a pair of rest areas where one rest area serves westbound or eastbound traffic. Paired rest areas are located either directly across the highway from each other or within a few miles. One rest area stands alone. The Prosser rest area serves both directions of traffic and is located in the median.

Rest Area list

County	Location Name	Mile [4]	Direction	Facilities	Misc
Kittitas	None
Yakima	Selah Creek	22	Westbound
	Selah Creek	24	Eastbound
Benton	Prosser	80	Both
Umatilla (Oregon)	None				End I-82

[edit] Weigh Stations

The Washington State Patrol (WSP) operates weigh stations (truck scales) in Washington. The WSP uses them to enforce commercial trucking laws. Weigh stations are located on I-82.
