  • el toro interchange

    The Orange County Transportation Authority (OCTA), in partnership with California Department of Transportation (Caltrans), is studying potential alternatives to improve the Interstate 5 (I-5)/El Toro Road Interchange. OCTA and Caltrans are working closely with the cities of Lake Forest, Laguna Hills and Laguna Woods.

    The project is in the environmental phase and the purpose of the project is to:

    • improve traffic flow and optimize traffic signalization;
    • reduce queuing at freeway on- and off-ramps; and
    • reduce congestion at and through local street intersections.
