California State Highways

The California state highway system is a network of roads that are owned and maintained by the California Department of Transportation (Caltrans). The system includes 16,475 miles of roads, which are designated with the prefix “SR”. State highways are typically numbered in a sequential order, with the exception of a few highways that have been given historical or geographical designations.

The California State Highway system was introduced in 1926, and has since grown to become one of the largest state highway systems in the United States. The system includes a wide variety of roads, from major freeways to rural two-lane highways.
