The southbound I-405 between Highway 101 to Getty Center Drive will be closed Monday and Tuesday starting at 10 p.m. The northbound lanes in the same area will be closed Wednesday and Thursday nights.
Ramps within the closure could start to close as early as 7 p.m. All lanes will be shut down by midnight, but will be re-opened by 5 a.m., in time for the morning commute. Sepulveda Boulevard will remain open next to the freeway during the closures as an alternate route. But it only has one lane in each direction in much of the work zone.
Crews are working on reconstruction of the Mulholland Bridge. Carpool and exit lanes are being added, and the entire freeway will be revamped between the 101 and the 10 freeways. The $1.2 billion project is scheduled to be completed next year, and is being run by the Metropolitan Transportation Authority in cooperation with Caltrans.
