As of 2004, the highway's northern terminus is in Boundary County, Idaho at the Canadian border, where it continues as Provincial Highway 95. Its southern terminus is in San Luis, Arizona at the Mexican border, where a short spur leads to Mexico Highway 2.
US 95 is one of the few routes with a designated "Spur" route. Spur US 95 runs from US 95 in Weiser, Idaho to a state highway junction in Washington, a distance of just 3 miles. It replaced a section of the former US 30N. US 30N itself had previously replaced US 630, a candidate for "shortest signed US highway."
US 95 also has an Alternative Route in Nevada.
