Washington State Route 231

The highway, located entirely west of Spokane in the Inland Empire, serves Sprague, Edwall, Reardan, Springdale, Valley and Chewelah.

[1] Traveling northeast, the highway traverses a hill and cliff, passing Browns Lake, and turns west.

The roadway briefly turns east as Main Street before crossing a BNSF Railway line and continuing northeast alongside the tracks.

SR 231 turns north at Aspen Street and crosses the Eastern Washington Gateway Railroad and a marsh via a causeway.

[6] SR 231 crosses Sheep Creek and the same railway as Second Street and leaves Springdale, parallel to the railroad, into a valley.

[14][15] State Road 3 became PSH 3 during the same year and a secondary route, SSH 3J, was also established to span from the Little Falls Dam at Long Lake to Springdale.

[17][18] Three years later, the Spokane River Bridge at Long Lake Dam was constructed and spanned from the southern terminus of SSH 3J to Lincoln County.

The Spokane River Bridge at Long Lake Dam , pictured here in 1993, was constructed in 1949 over the Spokane River and was designated as part of Secondary State Highway 3J (SSH 3J) during a 1963 extension. SSH 3J was replaced by SR 231 during the 1964 highway renumbering and was added to the National Register of Historic Places on May 24, 1993 before being repaired in late 2008.
