From Maryhill, the road curves northeast and later north to pass Centerville and bypass Goldendale to intersect SR 142. US 97 then turns northeast through Brooks Memorial State Park and entering the Yakama Indian Reservation passes over Satus Pass then coming out of the Cascades into the Yakima Valley passes the Toppenish National Wildlife Refuge and Toppenish, where it intersects SR 22 and Fort Road, which was SR 220 until 1991. After leaving Toppenish in a northwestern direction, the highway parallels the Tacoma–Pasco route of the BNSF Railway and the Interstate 82 (I-82) – US 12 concurrency briefly past Wapato and some minor roads to also parallel the Yakima River and enter Union Gap, where the roadway joins the I-82 and US 12 concurrency.
From the interchange in which US 97 joins the I-82 / US 12, numbered exit 37, the freeway interchanges with many minor streets in Union Gap and some major highways, including a state route, in Yakima, including Valley Mall Boulevard at exit 36, SR 24 and Nob Hill Boulevard at exit 34, Terrace Heights Way and Yakima Avenue at exit 33; at exit 31, US 12 ends its long concurrency at the southern terminus of SR 823. After leaving Yakima, the highway enters Selah and interchanges with SR 823 and Rest Haven Road and then later leaves the city after interchanging Selah Road to cross Selah Creek on the Fred G. Redmon Bridge. Approaching Ellensburg, the roadway interchanges with SR 821 at exit 26, Military Road at exit 11 and the northern end of SR 821 at exit 3 before entering Ellensburg.
