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 exiting Arbor Place turns right onto the ramp leading to southbound Valley View Ave. here (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.

The closed lanes of N. Firestone Blvd. at Valley View Ave. Soon a large amount of dirt will be deposited on this northeast corner to provide weight to settle the earth before construction of the Valley View Ave. Bridge at this interchange (below):


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:

Questions and Answers:

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

2. Will N. Firestone Blvd. also be rebuilt between Trojan Way and the I-5 on ramp?

Yes, but access between those two points will remain open during construction. The reconstruction will occur without a long-term closure.

3. 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.


: 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.
