## Route description

SH-9 begins just west of Deary at an intersection with SH-8, which continues toward Moscow and Helmer. The highway travels north-northwesterly through rural areas along the eastern edge of the Palouse Range for its entire course, generally following a former railroad last used by the BNSF Railway. SH-9 passes south of Avon and through Stanford before reaching the Palouse River near its northern terminus at SH-6 just west of Harvard. SH-6 continues onward to Potlatch and Saint Joe National Forest from the intersection.

## History

The Lewis and Clark Highway, from Lewiston eastward to Lolo Pass, was designated State Highway 9 in 1916 and construction began in 1920. Upon its completion in 1962, it became U.S. Route 12.

SH-9 was the last state highway in Idaho to be paved (though, as of 2012, Idaho State Highway 29 and Idaho State Highway 64 still have unpaved sections).
