Week of June 25, 2017 


Fence installation, vegetation removal and sound wall removal along the northbound I-5 Florence Avenue on-ramp, adjacent to Longworth Avenue, will continue next week. Once the sound wall removal operation is completed, crews will immediately begin work to construct the new sound wall.  A privacy fence has been installed along Longworth Avenue, adjacent to northbound I-5 freeway. This work will be conducted weekdays, between 7 a.m. and 3:30 p.m. Please be advised, this work may be loud and disruptive due to concrete demolition and removal, equipment noise, sound wall construction activities and truck back-up alarms.


Crews are performing nighttime drilling operations for CIDH (cast in drilled hole) piles on Pioneer Boulevard. This work will be ongoing for approximately three weeks and will require nightly closures on Pioneer Boulevard, between Imperial Highway and Crewe Street (shown in red on the map below; detour route highlighted in green), Sundays through Thursdays, between 9 p.m. and 6 a.m.

This information can also be found on the project Google map.

Crews have completed bridge demolition activity to remove the old Imperia Highway bridge at I-5.

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 disruptive 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.


Crews have begun work to reconstruct the sidewalk on N. Firestone Boulevard, between Rosecrans Avenue and Markdale Avenue. The sidewalk in this area, shown on the map below in red, will be closed for the duration of this work and there will be no pedestrian access while crews reconstruct the sidewalk to match the new street alignment. This work will be ongoing for approximately three months.

Rosecrans Avenue may be closed to all through traffic (motorists and pedestrians) in both directions underneath I-5, Monday through Fridays between 10 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.


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.
