US 97 (trunk)
Washington US 97, a continuation of Oregon US 97, starts on the Sam Hill Memorial Bridge across the Columbia River between Biggs Junction, OR and Maryhill, WA. From Maryhill, US 97 heads north to Goldendale, climbing up from the Columbia. After bypassing Maryhill on a 2 lane expressway, US 97 continues to climb to the top of Satus Pass, elevation 3107 feet, and descends along Satus Creek into the Yakima Valley.
At the south end of Toppenish, US 97 intersects with SR 22 and turns to the left. At Jct SR 22, US 97 turns left and becomes a 4 lane divided expressway via Wapato to Jct I-82/US 12 at Exit 37 in Union Gap. From Satus Pass to Ahtanum Creek at the south end of Union Gap, US 97 passes thru the Yakama Indian Reservation. From Exit 37, I-82/US 12/US 97 heads north to the north end of Yakima. At Exit 31, US 12 leaves I-82/US 97 and heads west. US 97 continues north on westbound I-82 to Jct I-90 Exit 110 on the SE outskirts of Ellensburg. From Exit 110, US 97 follows I-90 to Exit 106.
At Exit 106, US 97 leaves I-90 and heads north via Blewett Pass, elevation 4,102, to Jct US 2 near Peshastin, where US 97 joins US 2. US 2/US 97 becomes a 4 lane divided expressway and goes down the Wenatchee River Valley. At Cashmere, Business US 2/97 leaves US 2/97 and heads south on Applets Way to the downtown area. On the other end of town, the business route returns to US 2/97 at Cotlets Way. The expressway continues to Olds Station on the north side of the mouth of the Wenatchee River and the west side of the Columbia. US 2/US 97 interchanges with the south end of Alt US 97 at Olds Sation. US 2/US 97 head east across the Columbia River. The expressway ends and US 2/US 97 heads north along the east bank of the Columbia to Orondo. At Orondo, US 2 leaves US 97 and heads east, climbing away from the Columbia River. US 97 continues north to the vicinity of Beebe, crosses the Columbia River to the Chelan Falls area, and heads north along the west side of the Columbia. A few miles north of Chelan Falls, Alt US 97 intersects with US 97 and ends.
US 97 continues north to Pateros, curving to the east to Brewster, and crosses the Okanogan near its mouth. The Okanogan River forms the west boundary of the Colville Indian Reservation. East of the Okanogan, US 97 turns and heads north towards Okanogan and Omak. On the SE side of Omak, SR 20 joins US 97. US 97/SR 20 bypass Okanogan and Omak to the east on a 2 lane expressway. From Jct US 97/SR 20, Business US 97 heads west on SR 20 across the Okanogan River to SR 215 (Old 97). Between SR 155 and SR 215, US 97/SR 20 crosses the Okanogan River and leaves the Colville Reservation. At the NE edge of Omak, SR 215 and Business US 97/Business SR 20 terminate at Jct US 97/SR 20. 97/20 continues north for about 25 miles to Tonasket, where SR 20 leaves US 97 and heads east. US 97 continues north via Oroville to the Canadian Border, becoming BC 97 as it crosses the border.
Washington US 97 is 321.62 miles long.
Alt US 97 Toppenish-Wapato-Union Gap
US 97 originally headed north from Toppenish to Buena. At Buena, US 97 joined US 410. US 97/410 headed NW from Buena via Donald to Union Gap. In the mid 1950s SSH 3A, the more direct route from Toppenish via Wapato to Union Gap, was numbered Alt US 97. By the mid 1960s, US 97 had been rerouted from Toppenish via Wapato to Union Gap and the Alt US 97 designation was no longer used. Former US 97 from Toppenish to Buena became part of SR 22. Traffic from Buena to Union Gap is now served by I-82/US 12.
