The highway connects the Las Vegas area to the recreational areas of Mount Charleston in the Spring Mountains. Located in the Humboldt-Toiyabe National Forest, a portion of SR 157 has been designated a Nevada Scenic Byway. The route was originally State Route 39, and has origins dating back to the 1930s. Route descriptionState Route 157 is located 15 miles (24 km) north of Las Vegas. The route starts at its junction with U.S. Route 95 (US 95) where it heads west rapidly gaining elevation. Within a span of 20 miles (32 km) an elevation of 3000 feet (900 m) is gained with noticeable difference: temperatures drop, trees and shrubs become greener and more numerous and there is lasting snow cover during winter months. Part of the route is designated as a Nevada Scenic Byway. The highway's western terminus is past the village of Mount Charleston where it winds up the side of the mountain for a short distance before U-turning back. HistoryKyle Canyon Road has existed since at least 1933, having been established as a county road connecting Charleston Peak (in what was then Dixie National Forest) to State Route 5 (now US 95) at Tule to the east.[2] By 1935, the entire {{convert|21|mi|km}} of the highway had been paved and designated as State Route 39 by the state.[3] SR 39 appears to have remained unchanged for several years after being included in the state highway system. Its first major change occurred on July 1, 1976, when the route was renumbered to State Route 157 in the mass renumbering of Nevada's state highways.[4] This change was first reflected on official state maps in 1978.[5] In July 1998, the Nevada Department of Transportation designated SR 157 as a Nevada Scenic Byway. The scenic route encompasses the westernmost {{convert|13|mi|km}} of the highway within the national forest area.[6] Major intersections{{jcttop|state=NV|county=Clark|length_ref=[7]}}{{NVint|location=Mount Charleston|lspan=2 |mile=0.00 |road=Charleston Park |notes=Dead end }}{{NVint |mile= |road={{jct|state=NV|SR|158|name1=Deer Creek Road}} }}{{NVint |location=Las Vegas |mile=21.44 |road={{jct|state=NV|US|95|city1=Las Vegas|city2=Tonopah|city3=Reno}} |notes=Interchange under construction; future I-11 }}{{jctbtm}} See also
