High Quality Content by WIKIPEDIA articles! State Route 213 (SR 213) is the shortest state highway in the U.S. state of Washington. The 0.35-mile (0.56 km) long 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.
