    Project Overview

    The Costa Mesa (SR-55) Freeway is one of the most heavily congested freeways in Southern California, and future demand is only expected to increase congestion. The SR-55 serves as a vital link to other major freeway systems within Orange County, and it is the only freeway providing a direct north-south connection between Central Orange County and the Coastal Region. Currently, the SR-55 between Interstate 5 (I-5) and State Route 91 (SR-91) has three to four general purpose lanes, one carpool lane and some auxiliary lanes in each direction. This project proposes to improve mobility and reduce congestion, increase freeway capacity and improve traffic operations

    About the Project

    The project reduces congestion and improves traffic by adding one general purpose lane (regular lane) in each direction on SR-55 between I-5 and SR-22 and provide operational improvements at various locations on SR-55 between SR-22 and SR-91. The project identifies the Build Alternative as the Preferred Alternative. The Build Alternative would:

    • Add one regular lane in each direction between I-5 and SR-22;
    • Modify southbound on- and off- ramps at Katella Avenue;
    • Modify southbound off-ramp at Lincoln Avenue; and
    • Modify northbound and southbound off-ramps at Fourth Street
