State Route260 (SR260) is a state highway serving Franklin and Adams counties in the U.S. state of Washington. The highway begins at SR 17 west of Connell, and travels through the Washtucna Coulee to Kahlotus, forming the southern terminus of SR 21 and the northern terminus of SR 263, before a concurrency with SR 261 to SR 26 in Washtucna.

SR260 had previously existed as a gravel road between Connell and Kahlotus in 1916 and was designated as Secondary State Highway11A (SSH11A) from Yakima to Connell and Secondary State Highway11B (SSH11B) from Connell to Washtucna in 1937. SSH11A in the Connell area became an extension of SSH11B in 1957, which in turn became SR260 in the 1964 highway renumbering.

Route description

SR260 begins at an intersection with SR 17 west of Connell in rural Franklin County. The highway travels east and turns southeast into Connell, traveling over a rail line owned by BNSF Railway and used on the Amtrak Empire Builder route between Pasco and Spokane. After intersecting U.S. Route 395 (US395) in the busiest section of the entire route, a diamond interchange that received a daily average of 2,800 vehicles in 2011, the roadway continues east through the Washtucna Coulee and passes south of Sulphur Lake before entering Kahlotus. As SR260 passes through Kahlotus, it forms the southern terminus of SR 21, going north towards Lind, and the northern terminus of SR 263, serving the Lower Monumental Dam. The road exits the city travelling east to Lake Kahlotus and Washtucna Lake, paralleling the Columbia Plateau Trail northeast to the beginning of a concurrency with SR 261. The two highways enter the Adams County city of Washtucna and become Main Street before an intersection with SR 26, where SR260 ends and SR261 continues to Ritzville.

History

The current route of State Route260 (SR260) first appears in a 1916 map as a road between Connell and Kahlotus. The highway was designated as part of Secondary State Highway11A (SSH11A) from Yakima to Connell and Secondary State Highway11B (SSH11B) from Connell to Washtucna in 1937, during the creation of the Primary and secondary state highway system. SSH11A was re-aligned in 1957 and the route in the vicinity of Connell became part of SSH11B. During the 1964 highway renumbering, SSH11B became SR260, being unpaved from newly created SR 17 to a short concurrency with U.S. Route 395 (US395)

By 1981, the entire route was paved and the concurrency with US395 was removed and replaced by an intersection with a bypass of Connell. No major revisions to the route of SR260 have occurred since the 1980s. The western section of the highway between SR17 and Connell was considered for removal by a legislative committee in 1986.
