the northbound I-405. The foundation consists of approximately 250 cast-in-drilled-hole (CIDH) piles.

This activity includes augering large holes, installing forms and steel cages, and pouring concrete into the holes to form the piles.

Once this work is complete, crews will begin placing rebar, constructing forms and pouring concrete to construct the wall.

The work is ongoing from 7 a.m.-4 p.m. on weekdays and Saturdays, as needed through November.

Nighttime activities may also occur between 9 p.m.-6 a.m. Crews may mobilize equipment as early as 6 a.m., and some activity may occur at night. This work may be loud.
