Crews have begun work to construct the new sound wall along the northbound I-5 Florence Avenue on-ramp, adjacent to Longworth Avenue. Over the next three 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.

A portion of the sidewalk on Longworth Avenue, adjacent to the northbound I-5, has been closed to accommodate sound wall reconstruction. A chain link fence has been installed to close this area of the sidewalk from public access through the end of 2017. Crews have begun removing this portion of the sidewalk and the adjoining block wall, as they prepare to reconstruct the freeway sound wall at this location. This work  is currently on hold and will resume soon. Once work resumes, sidewalk/block wall removal work will take place weekdays between 7 a.m. and 3:30 p.m. and may be intermittently loud and disruptive due to concrete removal activities. The sidewalk will be restored once sound wall construction is complete. 


On Monday night, Aug. 14, crews began the nighttime demolition of the old Norwalk Boulevard / San Antonio Drive bridge. As part of this work, Norwalk Boulevard / San Antonio Drive will be closed nightly between Adoree Street and Olive Street. Please be advised this work will be loud and disruptive due to bridge demolition activity and equipment noise. Work will be performed Sunday through Thursday nights and is expected to be finished by the morning of Tuesday, Aug. 22.

On Tuesday, Aug. 15 and Wednesday, Aug. 16 the contractor will be performing nighttime operations to set forms for abutment walls and will close southbound Pioneer Boulevard traffic between Crewe Street and Imperial Highway.

On Sunday, Aug. 20 and Monday, Aug. 21 the eastbound lane on Imperial Highway between Adoree Street and South Frontage Road will be closed nightly for drilling operations. One westbound lane of Imperial Highway will remain open to traffic.

On Tuesday, Aug. 22, between 8:30 p.m. and 6 a.m., Imperial Highway will be closed, between Adoree Street and South Frontage Road for concrete operations.

 Closure areas are shown in red on the maps below; detour routes are highlighted in green. Unless otherwise noted, work will be performed between 9 p.m. and 6 a.m. 





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

Pile driving activity along I-5 at Pioneer Boulevard and Imperial Highway is ongoing; this work will be conducted weekdays between 7 a.m. and 3:30 p.m. and will be ongoing intermittently for approximately four 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.


***There are no closures scheduled on Rosecrans Avenue the week of Aug. 13.

Crews have begun 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


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


In the next two weeks, crews will close the southbound Valley View Avenue left hand turn lane to S. Firestone Boulevard. This will be a long term closure for approximately 18 months. Motorists will be detoured to go south on Artesia Boulevard to access southbound I-5 freeway on-ramp (shown in red on the map below; detour route highlighted in green).

Valley View Aug. 7

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.
