  • 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 Northbound I-5 Lane Closure

    Expect delays; please allow extra travel time. 

    Northbound I-5 will be reduced to three lanes from 9 a.m. to 2 p.m. on Tuesday, March 13, and Wednesday, March 14, from Avenida Vista Hermosa to Camino de Estrella. The daytime lane closures are necessary because of temperature requirements for striping work. Motorists should expect delays and use alternate routes if possible. 

    Please be advised, dates and times are subject to change if there is inclement weather or there are unforeseen operational factors.
