Washington State Route 140

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.

Route description

State Route 140 (SR 140) originated as 15th Street at an intersection with SR 14 in Washougal, located about 1.47 miles (2.37 km) east of the eastern terminus of SR 500 on the shoreline of the Columbia River. 15th Street traveled north through Downtown, crossing the Vancouver–White Salmon rail route of the BNSF Railway and intersecting the former alignment of SR 14, E Street, before turning northeastward onto 17th Street. The highway crossed the Washougal River out of Washougal in a large forest and became the Washougal River Road. The roadway paralleled the river northeast and later east into the forests and mountains of Skamania County until the river turned north.
