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.

Milestone dates:
First half of Valley View Ave. Bridge opened October 7, 2019.
New Valley View Avenue of ramp from southbound I-5 opened September 19, 2020.
Second lane on southbound side of Valley View Avenue Bridge and sidewalk opened September 18, 2020.
Completion of second half of Valley View Ave. Bridge: Revised to *mid 2022.
Completion of entire I-5 Valley View Ave. Interchange project: Revised to *mid-2022.

On northbound I-5 there are now four all-purpose traffic lanes on I-5 from north of Valley View Ave. to the Florence Ave. Bridge. Then there are three all purpose lanes, plus two auxiliary lanes connecting to the northbound and southbound I-605. Under the I-605 Bridge, I-5  reverts to four all-purpose lanes, plus a fifth auxiliary lane connecting traffic from I-605 to I-5. Then it reduces again to four all-purpose lanes.

On southbound I-5 there are now five lanes where traffic merges from the I-605 interchange until the Orr & Day railroad overhead. Then it changes to four all-purpose lanes until south of Alondra Boulevard, where it reduces to three lanes approaching the Valley View Avenue interchange project that remains under construction until mid-2022.

When the Valley View Avenue Project is complete in mid-2022, we will open the additional car pool / HOV (High Occupancy Vehicle) lanes to traffic. At that time:

  • On northbound I-5 there will be an HOV lane from Valley View Ave. to the Orr & Day railroad overhead.
  • On southbound I-5 there will be an HOV lane from south of the Florence Ave. Bridge to Valley View Ave.

On April 20, 2021, the final layer of concrete was poured on the middle section of the second half of the new bridge and then covered with tarps to allow the concrete to cure. Photos below:

In early April, crews started removing the lumber forms from the vertical stem walls and placing the across the deck of the middle section of the second half of the bridge as a base for the next layer (mat) of rebar. Aerial photos below:

In the third week of March 2021, the first layer of concrete was poured on the middle section of the second half of the Valley View Avenue Bridge. Photos below:

 

In March of 2021, workers secured lumber forms over rebar stem walls and placed a rebar mat across the deck of the bridge in preparation for the concrete pour.  Aerial video of construction site and bridge below:

On the night of Thursday, October 1, the first layer of concrete was poured on the north end of the second half of the new bridge. The concrete was covered with tarps while the concrete cures. Video below from October 7:

Pre-cast concrete slabs were placed on the Coyote Creek Bridge west of I-5. Video from October 7 below:

The brand new Valley View Avenue off ramp from southbound I-5 opened to traffic the morning of Saturday, September 19! A new signal at the top of the ramp where it meets the bridge allows traffic to turn right or left. Ground and aerial videos below:

A second lane opened to traffic on the southbound side of the Valley View Avenue Bridge on the morning of Friday, September 18. 18, along with the new sidewalk. Video below shows vehicles using both southbound lanes:

The contractor completed the first concrete pour on the deck of the second half of the north end of the bridge the night of Wednesday, August 19. They are now constructing rebar stem walls on the deck of the south end of the bridge. Photos and video below:

The old Valley View Ave. on ramp to southbound I-5 permanently closed at 7 a.m. on Tuesday, May 26. This will allow us to construct a bridge leading to the new southbound on ramp and to complete the new S. Firestone Blvd.

The old Valley View Ave. on ramp to northbound I-5 (near N. Firestone Blvd. and Gateway Dr.) closed permanently at 11:59 p.m. Monday, May 11. At 4:30 a.m. Tuesday, May 12, the new Valley View Ave. on ramp to northbound I-5 opened to the public, accessible directly from Valley View Ave.

Traffic traveling south on Valley View Ave. from Alondra Blvd. will be able to access the on ramp with a right turn.

Traffic traveling northwest on N. Firestone Blvd. will be able to cross over Valley View Ave. to the new on ramp.

However, traffic traveling northbound on Valley View Ave. will NOT be able to turn left onto the new on ramp until later in the project. Northbound Valley View Ave. traffic will need to continue to Alondra Blvd., then west to Carmenita Rd. and north on Carmenita Rd. to the on ramp to northbound I-5. Map below:

The new S. Firestone Blvd. opened between Artesia Blvd. & Alondra Blvd. (via Marquardt Ave.) on July 13. It runs under the Valley View Ave. bridge. Video and photo below:

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.

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:

  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.
