Interstate 82 - Route Description

Route Description

I-82 starts at an interchange with I-90 and U.S. Route 97 (US 97) in Ellensburg. At this point, I-82/US 97 start heading southeast towards Yakima. Before entering Yakima, I-82/US 97 intersects State Route 821 (SR 821) and State Route 823 (SR 823) while passing the Yakima Firing Center.

Just north of Selah, the freeway passes over Selah Creek on the Fred G. Redmon Bridge, the longest concrete arch in North America at the time of its opening, spanning 549 feet (167 m) long across the creek. From the bridge, I-82/US 97 passes from Selah into Yakima. In Yakima, I-82/US 97 join US 12 and intersect SR 24. After leaving Yakima and Union Gap, US 97 splits from I-82/US 12. I-82 then enters the Yakama Indian Reservation as it starts turning eastward towards the Tri-Cities. West of Toppenish, I-82/US 12 intersects SR 22, and then goes east past Zillah and into Granger, where it intersects SR 223.

After leaving both Granger and the Yakama Indian Reservation, the freeway continues east to Sunnyside, where the highway intersects SR 241. Then, I-82/US 12 turns southeast to pass Grandview and reach Prosser, where SR 22 intersects the freeway. From Prosser, the highway turns northeast into Benton City, where SR 224 and SR 225 intersect I-82/US 12. From Benton City, the freeway goes eastward towards Richland, when I-182 starts and US 12 joins I-182 into Richland. From the interchange, I-82 goes southeast around the Tri-Cities and joins US 395. After joining US 395, the freeway goes south and then west into Plymouth, where the highway intersects SR 14 and leaves Washington on the Umatilla Bridge over the Columbia River heading into Oregon.

After coming off the bridge, I-82/US 395 enter Umatilla, where US 395 exits off at the intersection with US 730. After leaving Umatilla, the highway goes southwest and passes the Umatilla Ordnance Depot before ending at I-84/US 30 southwest of Hermiston.
