Caltrans, the California Department of Transportation, has twelve districts covering the state. Southern California is broken up into four districts.
- Kern County – District 6 (covers more counties)
- Los Angeles / Ventura Counties – District 7
- San Bernardino / Riverside Counties – District 8
- San Diego / Imperial Counties – District 11
- Orange County – District 12
For general maintenance and traffic conditions, Caltrans offers a couple of different websites. I highly recommend their “Quickmap” for traffic conditions throughout the state. Traffic cameras, changeable message signs, CHP incidents, and more can be accessed via the site. There is also an Android phone app available for the Caltrans Quickmap. Look for a link on the Caltrans Quickmap website.

- Report A Maintenance Problem
- Report a Traffic or Work Zone Problem
- CHP Incident Reports
Caltrans also maintains a database of all their highways and bridges. These are great resources for determining highway construction dates, old alignments, and much more. They can be found on the Structures Maintenance site by clicking here. The logs are broken up by district.
County Highway Departments
County Highways are maintained by a separate agency in each county. These agencies maintain most of the roadways outside of incorporated cities, though some cities contract with the county for maintenance. Within these websites, you can find all sorts of valuable data, such as construction projects, closures, detours, and maintenance requests. I highly recommend contacting the agency closest to you should you have any problems with potholes, signs, or other issues. Most agencies do respond quickly to these problems and doing so can help create safer roadways for us all.
- Kern County
- Los Angeles County
- San Bernardino County
- Riverside County
- Orange County
- San Diego County
- Imperial County
- Ventura County
Some of these county agencies also have publicly available bridge and highway logs. Each county has a different format for their data, so don’t expect bridge and pavement dates for all of them. Agencies with online road and bridge logs are listed below with links to the appropriate sites.
- San Diego County – Road Log
- San Bernardino County – Road Book
- Riverside County – Road Book – Maps
- Ventura County – Road Inventory
There are numerous incorporated cities throughout Southern California. Consult your local phone book or go to our Civic Information pages to find their website. Most cities have some method of reporting road problems. Larger cities, such as Los Angeles and San Diego offer an online method. I’ve had great success with the City of San Diego using their online maintenance form.
