  • I-5 (SR-73 to El Toro Road)

    Project Contacts 1 of 2

    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 and Caltrans are working together to implement the San Diego Freeway (I-5) Widening project from SR-73 to El Toro Road.

    Located adjacent to the cities of Mission Viejo, Lake Forest, Laguna Hills and Laguna Niguel, this $580 million freeway improvement project was approved by Orange County voters in November 2006. Once construction begins, the project will be built in three segments and include numerous roadway, structural and operational improvements, some of which are highlighted below:

    ROADWAY

    • New northbound and southbound general purpose lane from Avery Parkway to Alicia Parkway to increase capacity
    • Extension of the second carpool lane from Alicia Parkway to El Toro Road, in both directions

    STRUCTURE

    • Reconstruct two interchanges, as well as widen bridges
    • Modify multiple on- and off-ramps
    • Add new sound and retaining walls

    OPERATIONAL

    • Convert carpool lanes throughout project limits to continuous access, to facilitate entering and exiting throughout the corridor
    • Add new and re-establish auxiliary (merge) lanes, improving merging and diverging
    • Install new overhead signage and lighting
    • Restripe within project limits

    DETAILS

    • LENGTH: 6.5 miles
    • ADJACENT CITIES: Mission Viejo, Lake Forest, Laguna Hills, Laguna Woods, Laguna Niguel, San Juan Capistrano
    • TOTAL ESTIMATED COST: $580 million
    • SCHEDULE: Mid 2019 – 2025

    Construction started on the Sienna Segment (aka Segment No. 2) in mid-2019.

    Construction on the Orange segment, from approximately SR-73 to Oso Parkway, is estimated to start in early 2020.

    Construction on the Palm segment, the project’s northernmost segment, is planned for mid-2020.

    IMPORTANT NOTICE
    NIGHTTIME BRIDGE DEMOLITION AT I-5 and LA PAZ RD
    Weekend of Friday, November 15, 2019

    As part of the voter-approved I-5 Freeway Widening Project in south Orange County, construction crews will demolish the loop on-ramp/bridge to northbound I-5 from La Paz Rd in the City of Mission Viejo the weekend of Friday, November 15, 2019.

    At this time, the schedule to demolish the loop on-ramp/bridge is as follows:

    DEMOLITION NIGHT #1
    10 p.m. Friday, November 15 to 8 a.m., Saturday, November 16, 2019

    DEMOLITION NIGHT #2
    10 p.m. Saturday, November 16 to 8 a.m., Sunday, November 17, 2019

    Mandated Closure of La Paz Rd. at the I-5 Freeway

    To maximize safety, La Paz Rd. must be closed in both the westbound and eastbound direction at the I-5 Freeway during the two nights of demolition.

    Safe, approved and direct detours will be in place to guide motorists around the demolition/construction zone.

    La Paz Rd. will re-open to traffic at 8 a.m. on both Saturday, November 16 and Sunday, November 17, 2019.

    Expect Construction Noise

    This demolition operation will cause noise. However, the project team will be implementing a plan to demolish structures as safely, strategically and swiftly as possible.

    Please note that demolishing activities must take place at night when closure of freeway lanes and local streets are authorized by state and local agencies.

    Public Outreach

    Leading up to the demolition, public outreach will include, but not been limited to: project webpage, city updates, email blasts, social media posts, canvassing of informational fliers, installation and activation of portable changeable message signs and stakeholder/business outreach.

    Improving I-5 and Reconstructing the La Paz Rd Interchange

    The demolition of the loop on-ramp/bridge to northbound I-5 clears the way for crews to start widening the roadway in the northbound direction and reconstructing the La Paz Rd. Interchange.

    When the project is completed, the I-5 Freeway will include a 5th general-purpose lane and La Paz will include added vertical clearance, dedicated right-turn lanes as well as standardized shoulders, bicycle lanes and sidewalks.
