Boulder Highway is a 17 mile divided roadway in the Las Vegas metropolitan area, Nevada, USA. It begins at Foothills Drive at the southeastern edge of the city of Henderson. It runs northwest through that city, and the towns of Whitney and Winchester. The Boulder Highway name ends at the Las Vegas city limit at Sahara Avenue. The highway continues northwest as Fremont Street for another mile, ending at the five points intersection of Fremont, Charleston Boulevard and Eastern Avenues. Fremont continues as an undivided road until it intersects with Las Vegas Boulevard, where it ends at the Fremont Street Experience pedestrian mall.
Originally, Boulder Highway began where U.S. Highway 93 and U.S. Highway 95 merge, east of Railroad Pass and west of Boulder City (about US-93 Milepost 11). This old section is also know as the Boulder Strip
It is signed as Nevada State Route 582. It was formerly known as US-93/US-95 before the completion of the Oran K. Gragson Expressway now designated Interstate 515, which also carries the 93/95 designation.
The section of Boulder Highway between Tropicana Avenue and Sahara Avenue is known as the “Boulder Strip”, in reference to the famous Las Vegas Strip to the west. The Boulder Strip contains Sam’s Town Hotel and Gambling Hall, Boulder Station, and several smaller casinos and motels.
