US&nbsp;12 enters the state at [[Lewiston, Idaho|Lewiston]], crossing the [[Snake River]] from [[Clarkston, Washington]]. It ascends the [[Clearwater River (Idaho)|Clearwater River]], running concurrently with [[U.S. Route 95|US&nbsp;95]] for {{convert|7|mi|km|spell=in}}. It reduces to a two-lane undivided highway with signs that read "winding road next {{Convert|99|mi|km|disp=sqbr}}" and goes on to [[Orofino, Idaho|Orofino]], continuing up the middle fork of that river to [[Lowell, Idaho|Lowell]], the junction of the [[Lochsa River|Lochsa]] and [[Selway River|Selway]] rivers. It continues up the Lochsa and climbs to [[Lolo Pass (Idaho–Montana)|Lolo Pass]] at the [[Montana]] border. This portion of the highway is also designated as part of the [[Lewis and Clark National Historic Trail]]. Most of the highway in Idaho is within [[Clearwater National Forest]]. The eastern section of US&nbsp;12, through remote mountain forest and up to Lolo Pass, was built in the early 1960s, making it the last [[U.S. Highway]] constructed. No services are available between Lowell and Powell, about {{convert|70|mi|km}} further east.
