State Route 573 (SR 573) comprises two sections of Craig Road, a major east–west arterial roadway in the Las Vegas valley.

The first section of SR 573 begins at the Craig Road interchange with U.S. Route 95. From there, it proceeds eastward to the Las Vegas–North Las Vegas city limits at Decatur Boulevard.

The second section of SR 573 resumes at the intersection of Craig Road and Frehner Road, just east of the eastern city limit of North Las Vegas. From this point, the highway continues east on Craig Road over Interstate 15 to its terminus at Las Vegas Boulevard (SR 604) at the main entrance to Nellis Air Force Base.

Previously, the portion of Craig Road within North Las Vegas (between Decatur Boulevard and Losee Road) was a part of SR 573. This section was decommissioned in 2002 and turned over to the City of North Las Vegas, which promptly reconstructed the roadway.

The entire route is in Clark County.

RTC Transit Route 219 functions on this road.
