SR 170 begins at theInterstate 15 (I-15) Riverside interchange (exit 112), approximately 60 miles (97 km) northwest ofLas Vegas inVirgin Valley. From there, the two-lane highway meanders southeasterly approximately 3 miles (4.8 km) before reaching theRiverside townsite and theVirgin River. The route crosses the river, then turns northeasterly to somewhat parallel the south side of the river. The highway travels about 6 miles (9.7 km) before reaching the town ofBunkerville. After another 2 miles (3.2 km), the highway turns due north, crosses the Virgin River again, and enters the city ofMesquite. The highway travels about one more mile (1.6 km) northward through the southern portion of the city before ending at an intersection with Mesquite Boulevard (formerSR 144).[1][2][3]
A gravel road approximating the alignment of present-day SR 170 appeared on official state maps by 1933. This road was marked as part of State Route 6 andU.S. Route 91—these designations traversed the southern portion of the state from the California state line to the Arizona state line at Mesquite via Las Vegas.[4] The road in this area was fully paved by 1934.[5] By 1955, a shorter, multi-lane highway had been constructed to bypass Bunkerville to the northwest. US 91 (and SR 6) were relocated from Riverside Road to the new alignment, which would later becomeI-15.[6][7]
In 1976, the Nevada Department of Transportation began an effort torenumber its state highways. In this process, Riverside Road would again be designated a state highway, State Route 170. This designation was applied on July 1, 1976, and was first seen on state highway maps in 1978.[8][9] The route has remained relatively unchanged since.
