Rainbow Boulevard begins south of Blue Diamond Road (SR 160) in Clark County and continues north to Horse Drive in northern Las Vegas.

[3] SR 595 begins at Tropicana Avenue and proceeds north along Rainbow Boulevard for 5.495 miles (8.843 km) to Interstate 11/U.S.

The road got its current name sometime after US 95 (Oran K. Gragson Freeway) was built within the area (a separate Lorenzi Street exists just east of it, from Westcliff to Charleston).

In January 2003, the southern terminus of SR 595 was at State Route 160 (Blue Diamond Road), giving the highway a total distance of 10.846 miles (17.455 km).

RTC Transit Routes 101: Rainbow and 219: Craig (continuations of each other north and west respectively) function on this road.
