The portion of the Valley View Ave. Bridge over I-5 now connects to the pier wall west of S. Firestone Blvd. Workers have been installing the rebar support frame. The next step will be to build wooden molds over the rebar to pour concrete, as we recently did with the section of the bridge over Arbor Pl. Photos below show the progress between August 7 and August 14. (Tap / click on photos for slide show and details):


The concrete pour of the vertical stem walls on the deck of the Valley View Ave. Bridge over Arbor Place is complete. Workers have been removing the lumber molds and re-purposing them to use lay horizontally and build the upper surface of the bridge deck and installing deck drainage. That surface will be covered with a rebar frame and then concrete. Photos below show progress from August 7 and August 14:


Compacting and grading continue as we construct the new portion of  N. Firestone Blvd. between Trojan Way and Knott Ave. Photos below from August 14:



Workers are building the rebar frame for the pier wall that will support the new bridge over Coyote Creek. Photos below show crane lowering rebar on August 14:











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.
to access Valley View. They must turn right onto N. Firestone Blvd.

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. N. Firestone Boulevard will be rebuilt to the east. Closure and detour map below:


The city of La Mirada has requested increased assistance from the La Mirada Sheriff’s Department enforcing the traffic regulation prohibiting large trucks from using N. Firestone Blvd. between the I-5 on and off ramps and Valley View Ave. Caltrans will secure enforcement assistance from the CHP and will be be adding more signs to divert large trucks from the restricted portion of roadway.

Questions and Answers:

1. When construction is complete, will S. Firestone Blvd. still run through from Valley View Ave. to Artesia Blvd.?

2. When N. Firestone Blvd. is re-opened between Knott Ave. and Trojan Way, will traffic signals be installed at those two intersections?
The construction plans currently provide for stop signs only. Any changes would need to be requested by the city of La Mirada.

3. Will N. Firestone Blvd. be rebuilt from Trojan Way all the way to the I-5 ramps?

: Due to the dynamic nature of construction, please note that all dates and times are subject to change due to unforeseen operational factors or inclement weather.
