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).
