Intermittent traffic control is scheduled from 7 a.m. to 4 p.m. every day from Monday June 25 through Friday, June 29 to stripe and move K-rail at the following locations:

  • Valley View Ave. between Alondra Blvd. and Park Place.
  • N. Firestone Blvd. from the I-5 ramps to Valley View Ave.
  • N. Firestone Blvd. between Trojan Way and Phoebe Ave.
  • Trojan Way between Desman Rd. and N. Firestone Blvd.

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.

Crews have completed construction of the rebar framework across most of the deck of the Valley View Ave. Bridge over I-5. The contractor poured the concrete facing over the rebar frame of the bridge pier wall west of I-5. Workers are also constructing walls of rebar to provide structural support across the section of the bridge from the railroad tracks to the new ramp at Arbor Place.

The recently constructed and elevated portion of N. Firestone Bl. from Trojan Way to the end of work zone south of Phoebe Av. and of Trojan Way at N. Firestone Bl. is now open to traffic. Photos below:

The “old” intersection of Trojan Way at N. Firestone is now closed to through-traffic and will be available only to delivery trucks for Hawaiian Express and Numark. (below):

Construction of the section of the Valley View Av. Bridge west of I-5 between the railroad tracks and the Arbor Place on ramp continues as workers build rebar walls across the deck for structural support. Pictures of progress from June 5, June 12 and June 19 below):

This week the  contractor continued building a surcharge on the northeast corner of N. Firestone Blvd. at Valley View Ave. (below). A surcharge is a large deposit of dirt that will compress the earth below it in preparation for the construction of the new, elevated section of N. Firestone Blvd.


The Arbor Place detour is in place as of Friday, May 11. Arbor Place is permanently closed at the old intersection with Valley View Ave. Traffic may turn right or left off of Valley View Ave. one-way onto Arbor Place under the bridge structure south of the railroad tracks. (There is a designated left turn lane on northbound Valley View Ave). Traffic will exit Arbor Place one-way using the new ramp that puts traffic onto eastbound Valley View Ave. See map below:

Traffic on Valley View Ave. now accesses Arbor Pl. under the bridge just south of the railroad tracks (below):

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:


On Monday, June 11, crews began pile-driving in the Coyote Creek channel near the intersection of Trojan Way and N. Firestone Blvd. Local businesses should expect vibration and noise during normal, daytime working hours.

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.
