    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 SR-55 between the I-5 and SR-91 has three to four general purpose lanes, one carpool lane and some auxiliary lanes in each direction. OCTA and Caltrans are conducting an environmental study for a project to add new lanes and modified ramps at two locations on the 7.5-mile stretch of SR-55 between I-5 and SR-91. In addition to a No-Build alternative, one Build alternative is being studied. The Build alternative includes:

    • Adding a general purpose (regular lane) in each direction between I-5 and SR-22 as well as auxiliary lanes between some ramps;
    • Modify southbound ramps at Katella Avenue;
    • Modify southbound ramps at Lincoln Avenue off-ramp.

    Anticipated Schedule
