'''Interstate&nbsp;182''' ('''I-182''') is an east–west [[List of auxiliary Interstate Highways|auxiliary Interstate Highway]] in the [[U.S. state]] of [[Washington (state)|Washington]]. It connects [[Interstate 82|I-82]] to the [[Tri-Cities, Washington|Tri-Cities]] region and crosses the [[Columbia River]] on the [[Interstate 182 Bridge]] between [[Richland, Washington|Richland]] and [[Pasco, Washington|Pasco]]. I-182 is {{convert|15|mi|km}} long and entirely [[Concurrency (road)|concurrent]] with [[U.S. Route 12 in Washington|U.S. Route&nbsp;12]] (US&nbsp;12). It also intersects [[Washington State Route 240]] (SR&nbsp;240) and [[U.S. Route 395 in Washington|US&nbsp;395]].

Business leaders in the Tri-Cities began lobbying for a freeway in 1958 after early alignments for I-82 were routed away from the area. I-182 was created by the federal government in 1969 as a compromise that would directly connect to the Tri-Cities area while allowing other traffic to bypass it. The project would also incorporate an existing proposal to build a bridge between Richland and Pasco at the site of a [[cable ferry]] that ran until 1931.

Construction on I-182 was to begin in 1971, but was delayed by [[freeway revolt|opposition from conservation groups]], disputes over interchange locations, and a federal freeze on highway funding in 1980. The first section to be built, over the [[Yakima River]] west of Richland, began construction in late 1980 and opened to traffic three years later. The Interstate 182 Bridge opened in November 1984 and linked to a longer section opened a month earlier in Pasco connecting to the existing US&nbsp;12 bypass. The final sections of the freeway, between I-82 and Richland, opened to traffic in March 1986.

The Tri-Cities region gained its first overland connection in July 1888 with the completion of the [[Northern Pacific Railway]]'s permanent bridge over the [[Columbia River]] between [[Kennewick, Washington|Kennewick]] and the new town of [[Pasco, Washington|Pasco]].<ref>{{cite web |last=Oldham |first=Kit |date=March 5, 2003 |title=First trains cross the Northern Pacific Railroad bridge spanning the Columbia River between Pasco and Kennewick on December 3, 1887. |url=https://www.historylink.org/File/5365 |work=[[HistoryLink]] |accessdate=September 3, 2021}}</ref> A [[Pasco–Kennewick Bridge (1922)|road bridge]] was opened nearby in October 1922 and became part of the [[Inland Empire Highway]] (State Road 3), a state highway created in 1913 to connect [[Ellensburg, Washington|Ellensburg]] to the [[Palouse]] and [[Spokane, Washington|Spokane]].<ref>{{cite news |last=MacNey |first=Malcolm |date=October 17, 1965 |title=Tri-Citians Celebrate When Old-Bridge Tolls Removed In 1931 |page=26 |work=Tri-City Herald}}</ref><ref name="HL-IEH">{{cite web |last=Kershner |first=Jim |date=October 9, 2013 |title=Inland Empire Highway |url=https://historylink.org/File/10644 |work=HistoryLink |accessdate=September 3, 2021}}</ref> The Inland Empire Highway was incorporated into the [[United States Numbered Highway System|national numbered highway system]] created in 1926, which divided it between several routes.

===I-82 routing dispute===

[[Interstate 82|I-82]] was added to the [[Interstate Highway System]] in October 1957 by the federal government, which allocated approximately {{convert|132|mi|km}} for the corridor from [[Ellensburg, Washington]], to [[Pendleton, Oregon]].<ref>{{cite news |date=October 21, 1957 |title=Federal 'Gift' Of Highway Surprises State Officials |url=https://www.newspapers.com/article/tri-city-herald-federal-gift-of-highwa/169015117/ |page=1 |work=Tri-City Herald |agency=Associated Press |via=Newspapers.com |accessdate=March 27, 2025}}</ref> The initial proposal from the federal government, which was approved by the Washington State Highway Commission in January 1958, would follow the [[Yakima River|Yakima Valley]] but bypass the Tri-Cities by turning south near [[Prosser, Washington|Prosser]] or [[Mabton, Washington|Mabton]] to cross the Columbia River near [[Boardman, Oregon]].<ref>{{cite news |date=January 22, 1958 |title=Pendleton-Ellensburg Highway Route To By-Pass Tri-City Area |page=2 |work=Tri-City Herald}}</ref> After the route was shifted east in 1958 to cross the Columbia River on the existing [[Umatilla Bridge]], business leaders in the Tri-Cities began lobbying for a longer freeway to directly serve the area.<ref>{{cite news |date=March 20, 1958 |title=Umatilla Crossing OK'd for Highway |url=https://www.newspapers.com/article/tri-city-herald-umatilla-crossing-okd-f/169015190/ |page=1 |work=Tri-City Herald |agency=Associated Press |via=Newspapers.com |accessdate=March 27, 2025}}</ref><ref name="TCH-May1963">{{cite news |date=May 21, 1963 |title=Highway Report Points To Tri-City-Backed Route |page=1 |work=Tri-City Herald}}</ref> In 1961, the state government ordered a feasibility study to examine a modified route that would serve the Tri-Cities, including the use of the Hanford Site to bypass the Yakima Valley.
