High Quality Content by WIKIPEDIA articles! U.S. Route 95 is a north?south U.S. highway in the western United States. Unlike many other US highways, it has not seen deletion or replacement on most of its length by an encroaching Interstate highway corridor, due to its mostly rural course. It is the primary north?south highway in both Nevada and Idaho.As of 2008, the highway's northern terminus is in Boundary County, Idaho, at the Canadian border crossing of Eastport, where it continues north as BC 95. Its southern terminus is in San Luis, Arizona, on the Mexican border, where a short spur leads to Mexican Federal Highway 2 at San Luis Río Colorado, Sonora.
