    The Final Design Phase
    The project is currently in the Plans, Specifications and Estimates (PS&E) phase, commonly referred to as the “Final Design” phase. In this phase, OCTA and Caltrans will refine the preferred alternative design and finalize the right-of-way needs in preparation for the construction phase.

Overview Tab Content:

  • Today, nearly 360,000 motorists travel I-5 daily between the San Joaquin Hills Toll Road (SR-73) and El Toro Road. Transportation planners expect traffic volumes to grow 25 percent by 2045. To address this travel demand, OCTA in partnership with Caltrans is implementing the San Diego Freeway (I-5) Widening project from SR-73 to El Toro Road to improve I-5 travel in southern Orange County.

    Project Improvements:

    • Add one general purpose lane in both the northbound and southbound directions from Avery Parkway to Alicia Parkway
    • Extend the second carpool lane in each direction from Alicia Parkway to El Toro Road
    • Reconstruct the Avery Parkway and La Paz Road interchanges
    • Construct new auxiliary lanes at 6 locations and reestablish auxiliary lanes
    • Modify on-ramps and off-ramps at 6 locations
    • Convert buffer separated carpool lanes to continuous access
    • Provide standard lane and shoulder widths throughout the majority of the project limits

    The project team is working closely with the cities of Lake Forest, Laguna Hills, Laguna Niguel, Laguna Woods, Mission Viejo and San Juan Capistrano to deliver the proposed improvements.
