Interstate 182 (I-182) is an east–west auxiliary Interstate Highway in the U.S. state of Washington. The state highway is an Interstate route, traveling around the city of Kennewick, the largest of the three Tri-Cities in Eastern Washington. I-182 passes through the cities of Richland and Pasco, located in Benton and Franklin counties, respectively. The four-lane freeway, which is concurrent with U.S. Route 12 (US 12) for its entire 15-mile-long (24 km) length, begins at an interchange with I-82 in the Horse Heaven Hills and runs through Richland, becoming concurrent with State Route 240 (SR 240). I-182 and US 12 cross over the Columbia River into Pasco on the Interstate 182 Bridge and become concurrent with US 395 before the former designation ends abruptly.
Route description
I-182 begins at Goose Gap, located between Badger Mountain and Candy Mountain in the Horse Heaven Hills,[4] at a trumpet interchange with I-82 and US 12 in unincorporated Benton County.[5] The four-lane freeway carries I-182 and US 12 concurrently northeast into Richland, where it intersects Queensgate Drive in a partial cloverleaf interchange.[6] The highway continues east across the Yakima River to a trumpet interchange with SR 240, forming a short concurrency with SR 240.[7] The concurrency ends at the following junction, a cloverstack interchange with George Washington Way, where I-182 and US 12 split off from SR 240, which continues southeast into Kennewick along the Columbia River.[8] The freeway continues northwest across the Columbia River on the Interstate 182 Bridge, also known as the Lee-Volpentest Bridges, which carry six lanes of I-182 on twin 1,500-foot-long (460 m) spans into Pasco in Franklin County.[9][10][11]
I-182 enters Pasco and turns 90 degrees southeast towards the city center after intersections with Broadmoor Boulevard and Road 68 at Gesa Stadium.[12][13] The freeway intersects US 395 in a trumpet interchange, beginning a third concurrency, and 20th Avenue in a partial cloverleaf interchange near Columbia Basin College and the Tri-Cities Airport, utilizing an eastbound collector-distributor lane.[14] I-182 continues east, forming the northern boundary of downtown Pasco, intersecting 4th Avenue before crossing over a BNSF-owned railyard.[15][16] The freeway reaches a cloverleaf interchange with SR 397, where US 395 splits off to travel north towards Spokane.[17] I-182 ends southeast of the interchange, while the roadway continues southeastward towards Burbank and Walla Walla as US 12.[10][11]
I-182 is defined by the Washington State Legislature as SR 182, part of the Revised Code of Washington as §47.17.020.[18] As a component of the Interstate Highway System,[2][3] the highway is listed as part of the National Highway System for its entire length,[19] classifying it as important to the national economy, defense, and mobility.[20] The Washington State Department of Transportation (WSDOT) maintains the freeway and designates the corridor as a Highway of Statewide Significance,[21] which includes highways that connect major communities in the state of Washington.[22] WSDOT also conducts an annual series of surveys on its highways in the state to measure traffic volume, which is expressed in terms of average annual daily traffic (AADT), a measure of traffic volume for any average day of the year. WSDOT calculated that the busiest section of I-182 is between its interchange with SR 240 and the Interstate 182 Bridge in Richland, where approximately 60,000 vehicles used the freeway on average each day in 2013; in contrast, the lowest traffic level on I-182 was 8,900 vehicles at its western terminus with I-82.[23]
History

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.[24][25] 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.[26][27] In 1923, by which time the entire road had been improved,[28] the highway became State Road 3 (Primary State Highway 3 after 1937), but retained its name.[29] By that time, all of the route of Interstate 182 became a part of US 410 and US 395; both were established in 1926.[30][31][32] When I-82 was approved in 1956, the Tri-Cities wanted an Interstate, since Interstate 82 bypassed the cities. Interstate 182 was the solution and created a connection to the Tri-Cities. Legally, I-182 is defined by the Revised Code of Washington § 47.17.372.
