2019 Region Highlights
US 395 and SR 240
The segments of US 395 and SR 240 in the Tri-Cities region are key commute and economic corridors. WSDOT classifies both as T-1 freight corridors, meaning that trucks carry over 10 million tons of freight on each corridor annually. The US 395 corridor between I-82 and I-182 includes a five-mile section in Kennewick with eight traffic signals as well as two smaller freeway segments. The SR 240 corridor between Stevens Drive/Jadwin Avenue and I-182, known as the Bypass Highway, has traffic signals along its full length.
