Traffic will always be challenging in a busy crossroads location such as The City of Brea. The City has a comprehensive program for streets over which it has jurisdictional control. However, three major connectors that serve the town are Caltrans highways. Funding and approval for projects related to the 57 Freeway, Imperial Highway and also Carbon Canyon Road are under State control. While the City will always work to support upgrades for these vital roads, it has no authority to approve new proposals. However, as possible, Brea collaborates with Caltrans, as well as its neighboring communities to improve connectivity and manage traffic resources wisely.


Several major roadways in Brea are under the authority of Caltrans. These are Imperial Highway, Carbon Canyon Road, and of course, the 57 Freeway. The City of Brea and the Orange County Transportation Authority work in cooperation with this State of California agency to help manage  operations and plan improvements for regional traffic needs. Periodic Caltrans notices are received and shared in Brea as possible. 

To get the most updated information about progress of various highway related projects, it is always best to contact Caltrans District 12.
