Week of May 11 - May 18, 2018

** UPDATE Thursday, May 17, 2018**

Caltrans is planning to open the Imperial Highway onramp to northbound I-5 in Norwalk to the driving public at 6 a.m. Wednesday, May 23, just in time for the holiday weekend. To prepare for that opening, all lanes of the northbound I-5 freeway will be closed from Norwalk Blvd to I-605 from 11 p.m. Tuesday, May 22 until 5 a.m. Wednesday, May 23. 

The Pioneer Blvd on ramp to northbound I-5 will close permanently at 9 p.m. on Tuesday, May 22. It will not re-open. (When the Imperial Highway interchange project is complete, it will have on and off ramps in both direction at I-5).  Pioneer Blvd will have some lane restrictions with possible flagging between Imperial Highway and Crewe Rd. from 9 p.m. Tuesday, May 22 to 5 a.m. Wednesday, May 23, but traffic will be allowed through. 


This project is 67% complete.

Projected date of completion for the Florence Ave. Bridge: *Updated to December of 2019.

Project date for completion of project: Late 2019.

The southbound I-5 is tentatively scheduled to have a full freeway closure from I-605 to Norwalk Blvd. from 11 p.m. to 5 a.m. the nights of Wednesday, May 16 and, if necessary, again the night of Thursday, May 17 to construct median barrier. 

These lane closures  are scheduled for separate nights and will re-open each morning. Please go to our Planned Lane Closure web page to confirm lane closures. 

Detour signs will be in place. Consider using the southbound I-710 (Long Beach Freeway) to eastbound State Route 91 (Artesia Freeway) as an alternate southbound route and westbound SR-91 to northbound I-710 as an alternate northbound route. 

Workers install "face forms" (molds) on the rebar frame of the retaining wall on the east side of I-5 north of the Florence Ave. Bridge. The next step is to fill the molds with concrete (below):

Imperial Highway is scheduled to be closed in both directions from Adoree St. to the frontage road along the west side of I-5 the nights of Sunday, May 13, Monday, May 14, and if necessary, Tuesday, May 15, to remove falsework (temporary structure supports). Imperial Highway will close each night at 9 p.m. and re-open each morning at 6 a.m. Use Florence Blvd. or Rosecrans Ave. as alternate routes.

I-5 from Silverbow Ave. north all the way up to Pioneer Blvd. is in varying stages of progress with crews spreading base (gravel), grading, compacting and paving. This activity includes compaction with a vibratory roller, so residents in the nearby neighborhoods may experience noise and vibration during the day.

As crews work on Imperial Highway, Norwalk Boulevard and Pioneer Boulevard and Pioneer Boulevard bridges at I-5, one lane in each direction may be closed on each street (at I-5) during the daytime, between 8:30 a.m. and 3:30 p.m.


Construction on this project is 97% complete. The work that remains will include landscaping, electrical work, striping and other finishing work.

The Arbor Place detour is in place as of Friday, May 11. Arbor Place is now closed at Valley View Ave. Traffic may turn right or left off of Valley View Ave. 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 using the new ramp west of Valley View Avenue. See map 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 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 to 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:


Demolition of the Coyote Creek Bridge on N. Firestone Blvd. is underway. This is within a closed construction area.

Questions and Answers:

1. 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.

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.

*DISCLAIMER: 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.
