The sign is in place directing delivery trucks onto the old portion of Trojan Way to the delivery driveway of Hawaiian Express and Numark. Trucks heading west on Trojan Way may cross the broken white line onto old Trojan Way to access the delivery driveway on the left (July 17, 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. Photos from July 17 (below):


The contractor completed building a surcharge on the northeast corner of N. Firestone Blvd. at Valley View Ave.  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. (Photos from July 10 below):


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.

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:


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.
