Interstate 82 (sometimes called I-82) is a 143.58 miles (231.07 km) long^[2][3][4] Interstate Highway in the states of Washington and Oregon. The road goes from Interstate 90 and U.S. Route 97 in Ellensburg, Washington southeast through Yakima, Washington, the Tri-Cities of Washington, and Umatilla, Oregon before ending at Interstate 84 in Hermiston, Oregon.^[5][6][7][8]

Since I-82 is north of Interstate 84, it breaks the rules for Interstate numbering. This happened because when Interstate 80N was renumbered to Interstate 84 in 1980, Interstate 82 became north of Interstate 84. The renumbering was part of a project to remove Interstates that have letters within their numbers.^[9]

The highway goes over Selah Creek on a bridge called the Fred G. Redmon Bridge. When this bridge was opened on November 2, 1971 it was the longest concrete arch bridge in North America.^[10][11] The bridge is 549 feet long when it goes above the creek.^[10][11] It is mostly north south despite ending in a 2

In 1999, the state of Oregon wanted to make Interstate 82 longer. They planned three different roads, but all of them were not chosen.^[12][13] The freeway also has a spur route, Interstate 182, which connects Interstate 82 to Richland, Washington and Pasco, Washington.^[14]
