Brea Canyon Road Widening Project

Document Description: The Project is intended to address congestion during the A.M and P.M. peak hours and is expected to enhance the Level of Service (LOS) from an existing LOS F to LOS A, substantially improving traffic flow through the Brea Boulevard/Brea Canyon area. Additionally, the Project is intended to address safety by improving the design of existing curves within the project limits and reducing the potential for motorist conflicts. This would be accomplished by widening Brea Canyon Road from two to four lanes (two lanes each direction, divided by median barrier/raised median), realigning five existing curves within the project limits, and installing a new traffic signal.
