AECOM (legacy Shimmick Construction) is performing this project, the first of three phases to add one HOV lane in each direction of Interstate 5 (I-5) in Orange County from Avenida Pico to San Juan Creek Road.

The addition of the HOV lanes will provide continuity of the I-5 mainline HOV network within the project limits; maximize overall performance by minimizing weaving conflicts at the termini of the HOV lanes and maintaining travel speeds for HOV lane users; provide intermittent auxiliary lanes, where needed, to relieve congestion at diverge and merge locations; minimize right-of-way acquisition; relieve congestion within interchange areas, on- and off-ramps, and at local intersections (including Avenida Pico); and reduce congestion on I-5 within the project limits. The project is scheduled for completion in 2018.
