Exit Numbering - CA Numbered Exit Uniform System

exit number sign example

In 2002, Caltrans started numbering freeway exits in California. The California Numbered Exit Uniform System (Cal-NExUS) numbered exit signs will help travelers navigate unfamiliar areas, determine distances, and track travel mileage. These numbered exit signs will be visible at night which increases highway safety.

Exits are numbered from south to north on north-south routes and west to east on east-west routes. Each exit number is determined by the number of miles it is from the beginning of the route. For example, on Interstate 5, exit No. 1 will be just north of the Mexican border. Numbering will continue all the way to the last off-ramp (EXIT 796) before the freeway enters Oregon, 796 miles north of the Mexico/California border along Interstate 5.
