The portion of the Valley View Ave. Bridge over I-5 now connects to the pier wall west of S. Firestone Blvd in Santa Fe Springs. 1700 cubic yards of concrete were poured onto the deck of the bridge the night of Monday, Sep. 17 to encase the vertical rebar support walls. Photos below are from September 10, September 17 (before pour) & 18 (after pour). (Tap / click on photos for slide show and details):


The final layer of concrete has been poured over the rebar deck surface of the Valley View Ave. Bridge over Arbor Place and west of I-5 in Cerritos. This is the surface over which vehicles actually will drive. The concrete is covered with tarps and moistened to allow proper curing. Photos below from September 17 (views facing north):


Workers are constructing the rebar frame for the pier walls that will support the new bridge over Coyote Creek. east of I-5 near Trojan Way in La Mirada. The Coyote Creek Bridge will carry the new lanes of I-5 and N. Firestone Blvd. They are also building and assembling lumber forms over the rebar. The next step will be to encase the rebar in concrete. Photos below are from September 17:

Valley View Ave. will be elevated to meet with the new Valley View Ave. Bridge. In turn, N. Firestone Blvd. will be elevated to meet Valley View Ave. In preparation for these modifications, N. Firestone Blvd. is now reduced to one lane in each direction between Gateway Dr. and Valley View Ave. Trucks over 2,500 lbs. and /or 25′ long are not permitted. Click “play” arrow below:

Trucks 2500 lbs. or more and / or at least 25’ long will not be permitted to:
• Drive on N. Firestone Blvd. between Valley View Ave. and Gateway Dr.
• Turn left or right onto N. Firestone Blvd. from Valley View Ave.
• Turn left from the northbound I-5 Valley View Ave. exit ramp at Gateway Dr.

Access to all local businesses will remain open.

Through the remainder of this project, there will be recurring closures of:
N. Firestone Blvd. between Valley View Ave. and Gateway Dr.
Valley View Ave. between Alondra Blvd. and Park Place.
Access to businesses within those closure parameters will ALWAYS be permitted. Secure the attention of workers on scene to allow access, if necessary.

N. Firestone Boulevard is CLOSED between Knott Avenue and Trojan Way in La Mirada until at least April of 2019 to prepare for the widening of I-5 and to allow demolition and reconstruction of the bridge over Coyote Creek.
