Valley View Avenue Interchange


Valley View Avenue Interchange

In mid-November  of 2016 Caltrans began construction on the Valley View Avenue Interchange Project, which will add a High Occupancy Vehicle and mixed-flow lane in each direction along approximately one and a half miles of I-5 at Valley View Avenue, from Artesia Boulevard undercrossing to North Fork Coyote Creek. The project extends through the cities of Buena Park, La Mirada, Cerritos, and Santa Fe Springs.

Three bridges will be reconstructed: the Valley View Avenue Bridge at I-5, the North Firestone Boulevard Bridge over Coyote Creek, and the I-5 freeway bridge at Coyote Creek. Lanes will be kept open on the Valley View Avenue Bridge during construction. There will also be improvements to the interchange at Valley View Avenue and adjacent frontage roads. The new bridge includes a railroad overpass.

Construction on this project is 50% complete.

Projected dates:
First half of Valley View Ave. Bridge opened: October 7, 2019.
Completion of second half of Valley View Ave. Bridge: Revised to *late 2021.
Completion of entire I-5 Valley View Ave. Interchange project: Revised to *late 2021.

The contractor drove steel pipe piles in to the ground west of I-5 and south of the bridge for the future abutment wall for Firestone Blvd. ramp where it will rise to meet the new bridge. Now they are constructing the foundation for the abutment wall and pouring concret the retaining walls. Videos below from November 5, 19, and 26:

We opened a new FOURTH freeway lane to traffic on northbound I-5 from Alondra Blvd. to the Orr & Day railroad overhead north of Imperial Highway. At that point, it narrows back down to three lanes. After completion of the Florence Ave. interchange, the northbound fourth lane will extend almost to to I-605. We also opened a fourth lane on southbound I-5 from north of Imperial Highway all the way to the Orange County line near Artesia Blvd. Map below:We


The first half of the new Valley View Ave. Bridge opened to traffic on October 7, 2019:

Access from Valley View Ave. to S. Firestone Blvd. (just north of the railroad tracks) is now permanently closed. However, S. Firestone Blvd. remains open to traffic between Marquardt Ave. and Artesia Blvd.

  1. The contractor constructed the soffit and the stem walls along the edge of the deck of the ramp that will connect Firestone Blvd. to the Valley View Ave. Bridge. The first and second layers of concrete have been poured. Photos below show progress from May through August 27:

    5. Workers constructed the “soffit” (deck underside) and stem walls along the sides for the Valley View Ave. off ramp from southbound I-5 connecting to the bridge. Concrete was poured on the soffit and over the stem walls. Then the final layer of concrete was poured. Photos below from June 11 through October 7:

Video below from Oct. 15 shows final layer of concrete:


  1. Construction of two bridges side-by-side over Coyote Creek east of I-5 near Trojan Way in La Mirada is complete. One bridge will carry new lanes of Firestone Blvd. and one will carry the new lanes of I-5. The contractor demolished the old Coyote Creek Bridge west of I-5 in La Mirada and has completed construction of the abutment walls that will support the new bridge. Photos below from August 6 through September 24:


  2. N. Firestone Blvd. is closed between Knott Ave. and Trojan Way to allow widening of northbound I-5, reconstruction of a new Firestone Blvd, to the east, and the reconstruction of Coyote Creek Bridge. Detour map below:
