Pile driving activity will be ongoing intermittently for approximately six weeks. Pile driving activity will take place weekdays between 7 a.m. and 3:30 p.m. Crews will begin this work along northbound I-5, then will move across the freeway to complete work along southbound I-5. While pile driving activity will only be performed during the day, night crews may move equipment to reposition the pile driving rig within the work area. Please be advised this work may be loud and disruptive due to equipment noise, construction lighting (when equipment is moved at night), and vibration and pounding related to pile driving activity.


The week of April 30 crews will be working at night in the center median of the freeway constructing the bridge column forms. Lanes on northbound I-5 at Florence Avenue will be reduced, Sunday night, April 30 through Thursday night, May 4 between 11 p.m. and 5 a.m., as crews work in the center median.  At least one lane on northbound I-5 will remain open, while the work is conducted. 



Pile driving activity along I-5 at Pioneer Boulevard is ongoing; this work will be conducted weekdays between 7 a.m. and 3:30 p.m. and will be ongoing intermittently for approximately three months. Please be advised this work may be loud and distruptive due to equipment noise, vibration, and pounding related to pile driving activity.

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



There are no closures scheduled the week of April 30.

Rosecrans Avenue may be closed to all through traffic (motorists and pedestrians) in both directions underneath I-5, Monday through Fridays between 9 p.m. and 5 a.m. Nighttime closures on Rosecrans Avenue will continue intermittently for the next six months. For detour information visit the project Google Map.



All work has been completed on the Carmenita Road Interchange project.


In order to completely signal work, Valley View Avenue will be closed to all traffic, between Alondra and Artesia Boulevards, from 8 p.m. Friday, April 28 through 5 a.m. Saturday, April 29. As part of this work, the southbound I-5 Valley View on-ramp will be closed.  Expect delays and use alternate routes.

Sunday, April 30 through Thursday, May 4 crews will be performing work in the center median along northbound and southbound I-5 between Artesia and Alondra Boulevards. In order to complete this work, there will be partial lane reductions on I-5 and the northbound and southbound I-5 Valley View on-and off-ramps may be closed between 7 p.m. and 5:45 a.m.

Pile driving and shoring activities are ongoing on the south side of Valley View Avenue. This work will be conducted weekdays during the daytime between 7 a.m. and 3:30 p.m.

Please be advised, the northbound I-5 on-ramp at Freeway Drive has closed permanently. The ramp is shown on the map below in red; the detour route is highlighted in green. Motorists will be detoured to continue west on Alondra Bouelvard, then north on Carmenita Road to access the northbound I-5 on-ramp.
