County Route R3 is also known by several other names along its route. Portions of the highway are called Sage Road, Cactus Valley Road, and State Street. Its southern end is SR 79 at Radec and its north end is SR 74.
At its north end in Hemet, it provides a major transportation route.
Historic information conflicts as to the date the route was defined. Some information indicates the highway was created in 1966, although other sources give a commissioning date of 1973. This is a former routing of SR 79. [2]
