Fence installation, vegetation removal and sound wall removal along the northbound I-5 Florence Avenue on-ramp, adjacent to Longworth Avenue, has been completed. Crews have begun work to construct the new sound wall. Over the next few weeks, crews will continue drilling CIDH (cast in drilled hole) piles along northbound I-5. This operation will be conducted weekdays, between 7 a.m. and 3:30 p.m.


Crews have completed nighttime drilling operations for CIDH (cast in drilled hole) piles on Pioneer Boulevard and will now move to Imperial Highway. This work will be ongoing for approximately five weeks and will require nightly closures on Imperial Highway, between Adoree Street and South Frontage Road (shown in red on the map below; detour route highlighted in green). Work will be performed Sunday through Thursday nights, between 9 p.m. and 6 a.m.

 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 more weeks. 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.


On Thursday, July 27, at 9 a.m. crews will begin work to reconstruct N. Firestone Boulevard, between the main entrance of Norwalk Village Mobile Home Park and Rosecrans Avenue. In order to reconstruct the street, the main driveway for the Norwalk Village Mobile Home Park will be closed to all traffic through fall 2017. While this driveway is closed, access to enter and exit the community will be maintained via the back driveway near the storage lot. There will be no through access to Rosecrans Avenue from N. Firestone Boulevard, while this work is being conducted. The closure area is shown on the map below in red; the detour route is shown in green


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.
