Inconvenience

Motorists traveling south on the 405 Freeway through West Los Angeles will be made to take a short detour during an early morning five-hour full directional closure on Friday, Dec. 27.

From midnight on Thursday, Dec. 26 to 5 am on Friday, Dec. 27, the I-405 Sepulveda Pass Improvements Project contractor is scheduled to implement a full directional closure of the southbound 405 Freeway traffic between Santa Monica Boulevard and National Boulevard.

The closures will facilitate the realignment of lanes to accommodate roadway widening and drainage work along the freeway median.

Lanes will begin to close at 10 pm on Thursday; Ramps will begin to close at 7 pm. Although the southbound 405 closure is only from Santa Monica Boulevard to National Boulevard, the Sunset Boulevard and Wilshire Boulevard southbound 405 on-ramps are also being closed as a traffic mitigation effort...
