Twelve Changeable Message Signs (CMS) located on most Los

Angeles County freeways began displaying information about the upcoming closure

of the San Diego Freeway (I-405) over the weekend of February 14-18.

The CMS notices began appearing the morning of Friday and will remain in effect

around the clock through the duration of the closure. Twelve additional

portable CMS signs will be placed at various freeway locations. Approximately

14 such signs also will be posted on various surface streets in Los Angeles


The planned 80-hour “Jamzilla” closure involves a complex paving operation

requiring the grinding, pouring and setting of several layers of concrete in

relation to the $1 billion northbound I-405 carpool lane project from the Santa

Monica Freeway to U.S. 101.

The closure operation consists of a partial

day-time lane reduction and a full night-time directional freeway closure on

the northbound I-405 between Getty Center Drive and Ventura Boulevard. The

closure area is approximately 5.6 miles long, or nearly two thirds of the

entire I-405 project area.

During daytime hours, two northbound lanes will

remain open while the remaining three lanes will be closed. During night-time

hours, all five northbound freeway lanes in this area will be closed. The

southbound I-405 will remain fully open during the day, but some southbound

lanes may be closed during night-time only paving operations.

Work is scheduled to begin Friday night, February 14

starting at 11 p.m.

and will last until Tuesday,

February 18 at 6 a.m.

“Caltrans knows from past experience how effective CMS signs are in conveying

information to the motoring public,” said Acting District 7 Director Carrie

Bowen. “We are using every means possible to ensure that people know to stay

away from the closure area and limit driving over Presidents’ Day weekend.”
