Business U.S. 95 is cosigned with SR 599 (Rancho Drive) in Las Vegas, Nevada. This distinction is noted on US 95 freeway signs and many maps (including those published by the Nevada Department of Transportation). However, no business route signs are posted along the highway itself, and relatively few SR 599 shields can be found on the route.
US-95 Spur starts at its terminus with US-95 in the southern part of the city of Payette and travels northward along S. Main Street Approximately 1.1 miles (1.8 km) then continues a short distance on S 7th St to its terminus at State Highway 52.
This was the original routing of US-95 through downtown Payette before it was rerouted to its current alignment east of downtown along 16th Street.
The route now known as US-95 Spur was previously known as U.S. Highway 630 and U.S. Highway 30N. U.S. Route 630 was an east–west United States highway. It was decommissioned in or around 1931. With a length of around three miles, it may have been the shortest signed US route ever. It was concurrent with US-30N for its entire length. An earlier route numbered US-630 was proposed from Echo, Utah (northeast of Coalville) to Ogden, Utah, but was never signed in the field. U.S. Route 30N was a split route off of U.S. Highway 30 and was coterminous with U.S. Highway 630 at its west end in Oregon. East of Weiser, it was concurrent with what is now US-95 to Fruitland, Idaho, where it reconnected with US-30.
