State Route 170 (SR 170) begins at SR 17 west of Warden and south of the SR 17 and SR 262 intersection. From SR 17, the highway travels east to cross two pairs of railroad tracks owned by Columbia Basin Railroad, which go south to Connell and north to Moses Lake,[3] to enter Warden. Once the roadway enters Warden, it is named 1st Street and later ends at Main Avenue.[4][5] The busiest segment of the road in terms of vehicle counts was between SR 17 and Warden, with a daily average of 2,800 motorists in 2007;[6] the busiest segment in 1970 was at Main Avenue, with a daily average of 2,100 motorists.[7]
