Overview

Tri Cities Washington Map

Interstate 182 connects the Tri-Cities in southern Washington with I-82 west to Yakima and south across the Columbia River into Oregon. Carrying U.S. 12 throughout its length, the freeway provides part of the route east to Walla Walla and a truck route to U.S. 395 northeast toward Spokane. I-182 serves commuter traffic through Richland, West Pasco, Pasco. I-182 also briefly combines with SR 240, which heads north to the US Department of Energy's Hanford site and southeast to the Columbia Center commercial areas in Kennewick.

A $3.9 million project between WSDOT and the city of Richland replaced the signalized intersection at Queensgate Drive and the eastbound ramps with Interstate 182 at Exit 3 with a roundabout. Built in conjunction with a second roundabout nearby at Queensgate Drive and Columbia Park Trail, the new traffic pattern was expected to improve traffic flow. Planned for five years, bidding for the work took place in February 2018, with subsequent construction underway through July 2018.1
