State Route 213 (SR 213) is the shortest state highway in the U.S. state of Washington. The 0.35-mile-long (0.56 km) unsigned highway serves Malott, a community in Okanogan County. Extending from U.S. Route 97 (US 97) over the Okanogan River via a bridge to First Avenue in Malott, the roadway is semi-complete, as state law designates that the road should extend to SR 20 southwest of Okanogan. First appearing in a map in 1954, SR 213 originated as a branch of Primary State Highway 16 (PSH 16) in 1959 and later SR 20 Spur in 1964. SR 20 Spur became SR 213 in 1973 because another SR 20 Spur was recently established in Anacortes.

U.S. Route 97 in the U.S. state of Washington is a 322-mile (518 km) route which traverses from the Oregon state line at the northern end of the Sam Hill Memorial Bridge in Maryhill, north to the Canada–US border in Okanogan County near Oroville. The highway serves major cities such as Goldendale, Yakima, Ellensburg and Wenatchee before continuing towards the Alaska Highway at the Yukon border as British Columbia Highway 97. Along the length of the roadway, US 97 is concurrent with State Route 14 in Maryhill, Interstate 82 (I-82) and US 12 between Union Gap and Ellensburg, I-90 briefly in Ellensburg, US 2 between Peshastin and rural Douglas County and SR 20 near Omak. An alternate route connects the highway with Chelan.
