Beginning Thursday, March 6, drivers can expect periodic single-lane alternating traffic on Steveston Highway overnights for approximately two months. This is required to safely conduct ground improvements and for road grading on the east side of the overpass. Drivers can expect short periods where lanes to the east of Highway 99 remain unpaved while road grading is conducted.
Starting the week of February 17 and lasting for approximately three months, crews will begin stone column installation and pile driving work in the southwest and southeast quadrants of the Project.
Occasional weekend work may be necessary to complete this stage of the Project. If needed, weekend work will be limited to the hours of 7 a.m. to 7 p.m. to minimize disruptions.
