State Route 140 (SR 140) was a state highway in Clark and Skamania counties in southwestern Washington. The highway began and ended at SR 14 in Washougal and Prindle, respectively, and followed the Washougal River and Canyon Creek. The roadway first appeared as Canyon Creek Road in a 1911 map and was designated Secondary State Highway 8B (SSH 8B) in 1937. SSH 8B was a spur route of Primary State Highway 8 (PSH 8), which became SR 12 in the 1964 highway renumbering. SR 120 replaced SSH 8B in the same renumbering and SR 12 was renumbered in 1967 to SR 14 after U.S. Route 12 was extended into Washington. SR 120 was also renumbered to SR 140, decommissioned in 1992.
