Welcome to Caltrans District 4

District 4 Public Affairs 510-286-4444

The Caltrans District 4 Office of Public Affairs provides information about Caltrans projects to the news media, government offices and the general public. Additionally, we host public meetings, informing local communities about planned transportation projects.

Caltrans District 4 is charged with maintaining over 1,425 miles of State Highway in nine counties that comprise the Bay Area. We receive thousands of inquiries on a monthly basis about traffic operations, ongoing construction, planned projects and maintenance issues associated with the State Highway System.

If we haven't spoken to you directly it doesn't mean that we have not, in some way, communicated with you. Through our interaction with the news media, we keep the public informed about all aspects of Caltrans.

We are here to answer questions for you. Call Public Affairs at 510-286-4444. If you would like to speak with a Public Information Officer during normal business hours, click here for a staff directory.
