The southbound 405 Freeway lanes will close between Santa Monica Boulevard and National Boulevard from midnight to 5 am tonight, March 24 and Tuesday, March 25,
This closure will facilitate the installation of a full-span freeway overhead sign, and the continuation of roadway widening activities at the freeway median.
Ramps will begin to close at 7 pm. Lanes will begin to close at 10 pm.

The following ramps will close:
— Southbound Santa Monica on-ramp
— Southbound Sunset on-ramps
