Note that ISTEA repealed the previous Federal-Aid System, effective in 1992, and established the functional classification system for all public roads.

Previous Federal Aid (pre-1992) categories: Federal Aid Interstate (FAI); Federal Aid Primary (FAP); Federal Aid Urban (FAU); and Federal Aid Secondary (FAS).
Current Functional Classifications (used for aid purposes): Principal Arterial (PA); Minor Arterial (MA); Collector (Col); Rural Minor Collector/Local Road (RMC/LR).
Until 1983, this route ran from Route 1 to Mac Arthur Blvd, and then along Mac Arthur Boulevard from Route 1 near Corona del Mar to San Diego Creek in Irvine.
In 1983, Chapter 849 changed the origin of the route and modified the routing to be "Route 5 near San Juan Capistrano to Route 405 via the San Joaquin Hills." It also noted that "Mac Arthur Boulevard from Route 1 near Corona del Mar to San Diego Creek in Irvine shall cease to be a state highway when the Route 73 freeway as described above is completed." This reflected the planned construction of the San Joaquin Hills Toll Road. In 2003, Chapter 525 removed the text about the former portion of the route. The portion of the current routing from near UC Irvine to I-405 was LRN 184, defined in 1933 (as was the remainder of the since deleted 1963 routing) Route 73 was not defined as part of the initial state signage of routes in 1934.
