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 Interstate 11/U.S.

From this point, the highway continues east on Craig Road where it has a junction at Interstate 15 and U.S. Route 93.

SR 573 eventually reaches its eastern terminus at Las Vegas Boulevard (SR 604) at the main entrance to Nellis Air Force Base.

This section was decommissioned in 2002 and turned over to the City of North Las Vegas, which promptly reconstructed the roadway.
