History
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 and U.S. Route 91
U.S. Route 91 or U.S. Highway 91 (US-91) is a north–south United States highway running from Brigham City, Utah, to Idaho Falls, Idaho, in the U.S. states of Idaho and Utah. Despite the "1" as the last digit in the number, US-91 is no lon ...
—these designations traversed the southern portion of the state from the California state line to the Arizona state line at Mesquite via Las Vegas. The road in this area was fully paved by 1934. 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 become I-15.
In 1976, the Nevada Department of Transportation began an effort to renumber 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. The route has remained relatively unchanged since.
