Week of March 16 - March 22, 2018


This project is 60% complete.

The City of Santa Fe Springs has tentatively scheduled the closure of Florence Ave. at the Florence Ave. bridge for three nights the week of Monday, Mar. 19. Details are pending.

Southbound I-5 overnight full freeway closures to pour concrete for bridge columns and column footings are scheduled for:

Each night Sunday, Mar. 18 through the night of Thursday, Mar. 22:

• Southbound I-5 all lanes closed from I-605 to Norwalk Blvd. from 11 p.m. to 5 a.m.
• Northbound and southbound I-605 connector ramps to southbound I-5 closed from 9 p.m. to 5 a.m.

These closures are scheduled for separate nights and will re-open each morning. If rain causes excessive flooding in the below-ground construction area, these closures will be postponed. Please go to our Planned Lane Closure web page for confirmation of each night at:

Please be aware that there is also an ongoing overnight repaving project on southbound I-5 between Washington Blvd. and I-605 Wednesday nights through Saturday nights as weather permits. At least one lane open at all times.

Detours signs will be in place. Consider using southbound I-710 (Long Beach Freeway) or southbound I-605 to eastbound State Route 91 (Artesia Freeway) as alternate routes.

Rebar for bridge columns and footings below ground in the median of I-5 north of the Florence Ave. Bridge pictured below:


The construction of both retaining walls and the bridge abutment along the Florence Ave. on ramp to northbound I-5 is almost complete. Once the retaining walls are complete, the area against the walls will be backfilled. Then construction of the sound wall on top of the retaining wall near Longworth Avenue can begin. Construction of sound walls along the east side of I-5 in this area are projected to be complete around August. Abutment and retaining walls (below):

Installation of a drainage system that will drain water from the east side of I-5  to the west side of I-5 is complete. This will alleviate flooding issues along Longworth Ave.


Construction on this project is 79% complete.

Upcoming changes:

  • Imperial Highway is scheduled to be closed from Adore Ave. to the Frontage Rd. on the night of Tuesday, Mar. 20 from 8:00 p.m. to 6:00 a.m. to allow a concrete pour on the top side of the Imperial Highway Bridge. The Imperial Highway off ramp from southbound I-5 will remain open, but traffic will only be able to turn right or to go straight. Detour map below:

  • Norwalk Blvd. / San Antonio Dr. is tentatively scheduled to be closed between Adore St. and Olive St. on the nights of Tuesday, Apr. 3, Wednesday, Apr. 4, and possibly Thursday, Apr. 5 from 8 p.m. to 6 a.m. to allow installation of girders across the second half of the San Antonio Bridge.(Detour map below).
  • This will also require the closure of up to two lanes on northbound I-5 from Silverbow Ave. to Pioneer Ave. and the northbound Norwalk Blvd. off ramp.

 I-5 from Silverbow Ave. north all the way up to Pionner 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. This past week crews have been paving lanes between the Imperial Highway Bridge and the Pioneer Blvd. Bridge (below):

  imperial 7 3-19-18

imperial 8 3-19-18

As crews work on Imperial Highway, Norwalk 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.

Upcoming changes: In April, Norwalk Blvd / San Antonio Dr, will be closed for two nights as we install girders across the second half of the San Antonio Bridge.

By *late April, the existing N. Firestone Boulevard will close for more than one year between Knott Avenue and Trojan Way in La Mirada for demolition 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. Private business access will only be permitted to Osmond Ave. In preparation, flyers will be distributed to businesses in the immediate area and signs will be placed in strategic locations in the neighborhood advising of the forthcoming closure. Map below:


Construction of two retaining walls south of the Valley View Avenue bridge by S. Firestone continues. Crews will pour concrete footings next week and continue abutment work on the Valley View Avenue bridge. .

*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.
