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 will include 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.

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. Map below:

In the next few weeks we will paint striping and open a fourth lane on the southbound side of I-5 from the Orr & Day railroad overhead north of Imperial Highway all the way to the Orange county line, where we will match the number of freeway lanes

Valley View Ave. re-opened to through-traffic between Artesia Blvd. and Alondra Blvd. at approximately 5:30 a.m. on Monday, Oct. 7. Caltrans and our contractors thank everyone for their patience and cooperation while we made improvements along the avenue.

The changes include:

1. The opening of the first half of the new Valley View Ave. Bridge crossing over I-5. There is one lane open to traffic in each direction. We plan to open a second southbound lane (for a total of three lanes) by the end of the year.
2. There is also a new pedestrian walkway on the west side of Valley View Ave. crossing over the bridge. Video below from Oct 7:

3. Arbor Place is now open to two-way traffic with a signal permitting turns in all directions. Video below from Oct. 7:
4. Large trucks and big rigs are now permitted to make turns in all directions at the intersection of Valley View Ave. and N. Firestone Blvd. with traffic signal control. Video below from Oct. 7:

New restrictions include:
1. 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.
2. The Valley View on-ramp to southbound I-5 from S. Firestone Blvd. is now closed as we add new lanes to the freeway.
3. For the business complex east of Valley View Ave. and north of Park Place, one of the two-way access driveways closed. However, a new road has been constructed to allow one-way traffic to exit the complex on the north end to access Arbor Place.
4. “Old” Valley View Ave. is now closed from the south end of the Valley View Ave. Bridge to the north end. The existing half of the old bridge is closed so that we may demolish and reconstruct it. Traffic on Valley View Ave. is now traversing the first half of the new bridge. Map below:

  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 has demolished the Coyote Creek Bridge west of I-5 in La Mirada. The contractor is finalizing construction of the abutment walls that will support the bridge. Photos below from August 6 through
  2. September 24:


  3. 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:
