Week of November 19, 2017 

In observance of the Thanksgiving holiday, there will be no closures from 6 a.m. Wednesday, Nov. 22 through midnight Sunday, Nov. 26. 



There are no closures scheduled on the Florence Avenue interchange project the week of Nov. 19. 

On Monday, Nov. 19 and Tuesday, Nov. 20, crews will continue work to construct the northbound I-5 Florence Avenue on-ramp and the adjacent sound wall. Work will be ongoing at the south end of the sound wall, nearest Florence Avenue. Construction activities will include (but not limited to) backfilling using a vibratory roller, forming sections of the wall, and pouring concrete. 

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. The sidewalk will be restored once sound wall construction is complete. While the sidewalk is being reconstructed, the sidewalk across the street from this work is open and accessible for public use.

On Tuesday morning, Nov. 28 crews will move into the next stage of construction on the Florence Avenue bridge (Stage 2 Phase 1). Traffic will be shifted onto the newly constructed south half of the Florence Avenue bridge and the new lane configuration will include two lanes for westbound traffic and one lane for eastbound traffic. 

To prepare for the traffic shift, Florence Avenue will be closed between Studebaker Road and Orr and Day Road from 8 p.m. Monday, Nov. 27 until 7 a.m. Tuesday, Nov. 28, at which time Florence Avenue will reopen with the new temporary lane configuration shown on the map below. Visit the project website for a map of alternate routes to use while Florence Avenue is closed overnight on Monday, Nov. 27.

In addition to the new lane configuration, crews will begin reconstructing the intersection of Orr and Day Road at Florence Avenue, to accommodate the new higher elevation of the Florence Avenue bridge. Please note, the intersection of Orr and Day Road, from Longworth Avenue to Florence Avenue, will be closed for approximately two months (weather permitting), beginning Tuesday, Nov. 28 at 7 a.m. While the intersection is closed, motorists will be directed to use an alternate route, as shown on the map below. 

The new temporary traffic configuration on Florence Avenue is shown on the map below; closure areas are shown in red. To view all of the construction staging maps for the Florence Avenue bridge, visit the project website


There are no nighttime closures scheduled on the Imperial Highway & Pioneer Boulevard project the week of Nov. 19.

Crews have closed the sidewalk along westbound Imperial Highway between Paddison Avenue and Pioneer Boulevard for construction activity. This portion of the sidewalk will be closed for the next several months. Pedestrians should follow detour signs and watch for motorists; the pedestrian detour route is shown on the map below in green; the sidewalk closure area in shown in red.

Imperial Closure 11-12-17

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.


There are no closures scheduled on Rosecrans Avenue & Bloomfield Avenue project the week of Nov.19.

Over the next few weeks, crews may take intermittent day lane closures on Rosecrans Avenue at Mondays through Fridays between 8:30 a.m. and 3:30 p.m. At least one lane will remain open in each direction on Rosecrans Avenue at all times. These lane closures are needed to complete installation of overhead signs and to pour curb and gutter.

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


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.
