California Highways: 
“Everything You
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 webmaster@cahighways.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 疫情之后的奢侈品市场会怎样？来看看贝恩的分析 - 知乎 - Zhihu:著名的贝恩公司（Bain & Company）在前几日发布的名为《Luxury after Covid-19》的报告中，就新冠疫情对全球奢侈品的影响做了一定的分析，并对疫情之后的发展进行了预测。该文章由五大专栏作家联手完 …, and if that doesn't work, please send me email at webmaster@cahighways.org. 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 summary of how the numbers of state highways have
changed. It focuses on two primary areas: the "great renumbering" in 1964
when the legislative route numbers were aligned with the signed route
numbers, and how the U.S. highway system has changed in California.

to the recommended reading lists. I
also maintain copies of Caltrans and
Related Resource Links for resources that disappeared during
Caltrans' 2024 accessibility rework.
This section provides a
summary of recent changes to the California Highway pages.
I couldn't have done it

folks that have helped me develop these pages. You may also want to look

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:
