Ever Wanted To Know About Numbered Highways in California*”
* But Were Afraid To Ask
Welcome to the California Highways home page. From this page, you can access a variety of information related to California highways and California highway history that I have collected over the years. I welcome comments and corrections to this information; you may reach me by sending Email to firstname.lastname@example.org.
This site should answer most of your questions. However, there still may be a few questions that aren't covered by the areas in the site. If you question remains unanswered after reviewing the site, please check the Other Frequently Asked Questions, and if that doesn't work, please send me email at email@example.com. Another good source to getting questions answered is Caltrans itself (and you must use the Caltrans contacts if the question relates to potential legal issues).
Note: This is a hobbyist website. The California Highways Site is not affilated with or sponsored by Caltrans, the California Department of Transportation, although I truly appreciate the support that Caltrans staff have provided me in doing research, and the kind words they have sent me regarding the information on this site. If you have questions concerning operation of the state highways, or that are of a legal or regulatory nature, please contact Caltrans directly at http://www.dot.ca.gov/. I'll be glad to answer any question I can, but this is a hobbyist site. If you are looking for the current status of a particular state route, try the Caltrans Highway Status page. The California Highway Patrol also maintains a Traffic Incident Page. If you have a maintenance problem to report, use the Caltrans Maintenance Report Form.

This section provides a history of additions and changes to the state route system. They identify, year by year, when each portion of a route was added or deleted to the state highway system.

I also maintain copies of Caltrans and Related Resource Links for resources that disappeared during Caltrans' 2019 accessibility rework.
This section provides a summary of recent changes to the California Highway pages.
I couldn't have done it without you. No, really! This section provides credit to all the good folks that have helped me develop these pages. You may also want to look at the recommended reading lists.
Additionally, the following sites are part of the cahighways.org family. Although not maintained by the cahighways.org webmaster, they all deal specifically with California and its highway system:
aaroads.cahighways.org. Formerly limited to just San Diego, Andy Field and the crew at AARoads have expanded to cover all of California.
santa-clarita.cahighways.org. Mike Ballard's "Historical Highways of Central and Southern California" pages. This includes information on US 6 and US 99, as well as information on unbuilt freeways, maps, East Los Angeles interchanges, and much, much more.
ushighways.cahighways.org. Casey Cooper's "Historic US Highways of California". The historic US highways of California have the same magic that Route 66 has, although much of theirs is still waiting to be rediscovered. This site is a repository of information about the 18 US highways that once traversed California.
