  • Overview

    This 5.7-mile project extends from Avenida Pico in San Clemente to San Juan Creek Road in San Juan Capistrano. The four-year, $230 million project will:

    • Add a carpool lane in both directions on I-5 from Avenida Pico to San Juan Creek Road;
    • Improve the sight distance on the southbound curve north of PCH;
    • Reconstruct the interchange at Avenida Pico, including widening the northbound Avenida Pico on-ramp to three lanes, and providing dual left-turn lanes to both on-ramps; and
    • Add sound walls where needed.

    Purchase on Pico

    We are committed to assisting local businesses during the reconstruction of the I-5 / Avenida Pico Interchange in San Clemente. Businesses are invited to participate in our “Purchase on Pico” Program, free of charge.


    This $230 million project is funded in part by Measure M2, Orange County's half-cent sales transportation tax. In addition, OCTA is funding the work with a combination of Measure M2 local sales tax and state and federal funding.


    The project is being constructed in three segments: Avenida Pico to Avenida Vista Hermosa; Avenida Vista Hermosa to Pacific Coast Highway; and Pacific Coast Highway to San Juan Creek Road.

    Flatiron Construction began work on the first segment, focused on the Avenida Pico Interchange, in February 2015. Work on the second segment, also being done by Flatiron, started in September 2014 and includes construction of retaining walls and sound walls, as well as on- and off-ramp improvements. Shimmick Construction has the third segment, centered primarily on the PCH / I-5 interchange, where work began in February 2014.


Detours Tab Content:

  • Daytime Closure at Vista Hermosa

    The outside lane of northbound I-5 at Avenida Vista Hermosa as well as the off-ramp there will be closed during the following times:

    • Avenida Vista Hermosa off-ramp: 10 p.m. Monday, Dec. 12, to 5 p.m. Tuesday, Dec. 13
    • NB I-5 outside lane at Avenida Vista Hermosa: 10 a.m. to 3 p.m. Tuesday, Dec. 13

    The closure must be performed in part during the day due to temperature requirements for paving. Motorists should use the Avenida Pico off-ramp as a detour. The Pico on-ramp to northbound I-5 will not be affected.

    Estrella Closure, Detour to End

    The extended closure of the Camino de Estrella loop on-ramp to northbound I-5 is set to end on Saturday morning, Dec. 10. In addition, the temporary detour from the northbound I-5 Camino de Estrella on-ramp to Camino Las Ramblas will be removed by Saturday morning. Motorists again will be able to merge onto the northbound I-5 directly from the Camino de Estrella straight on-ramp. In order to remove the detour, crews will need to close the straight on-ramp two hours earlier than normal on Friday, Dec. 9, at 8 p.m.
