Idaho State Highway 64

SH-64 begins at a junction with SH-62 and SH-162 in downtown Nezperce. The highway heads east from here, passing Nez Perce Municipal Airport. In eastern Nezperce, the route turns north along Beech Street before leaving the city to the northeast. Outside of Nezperce, the highway heads east through ranchland as a two-lane paved road. The route passes several local roads before curving to the southeast. Along the southeast leg, the road has an unpaved gravel surface for three miles and runs along the side of a mountain. Past this stretch, the highway turns briefly to the east before twisting northward, where it passes through a forested area. The route passes a group of houses before making a sharp turn to the south. From here, the highway follows a winding path into Kamiah. In Kamiah, the road passes southeast through a residential area parallel to U.S. Route 12; while the two highways do not intersect, they are connected by local streets. According to ITD, SH-64 officially ends at a junction with SH-162 in Kamiah; however, highway signage indicates that the highway follows SH-162 for several blocks before terminating at US 12.[1][2]

The entire route is in Lewis County.
