Overview of Lane Closures
Starting Friday, March 20, at 10 p.m. and continuing until Monday, March 23, at 5 a.m., significant lane reductions will take place on the Interstate 405 (I-405) Freeway through the Sepulveda Pass. The California Department of Transportation (Caltrans) has announced that both northbound and southbound traffic will be reduced to three lanes between Getty Center Drive and Skirball Center Drive. This construction is part of the ongoing I-405 Pavement Rehabilitation Project, which aims to enhance safety, mobility, and extend the lifespan of the roadway.
Details of the Construction
During this extended weekend closure, the northbound I-405 will be restricted to three lanes from just south of the Getty Center Drive off-ramp to just north of Bel Air Crest Road. Simultaneously, the southbound lanes will be reduced from the Skirball Center Drive on-ramp to the Getty Center Drive on-ramp. Notably, the Getty Center Drive on- and off-ramps will be completely closed during this period.
Caltrans has indicated that this is the first of 26 planned weekend closures as part of the $143.7 million project, which has been ongoing since June 2023. The project is designed to improve long-term road safety and traffic flow in the area.
Recommended Detours
To mitigate traffic congestion, Caltrans recommends that drivers consider alternate routes. For northbound traffic, drivers can take Sepulveda Boulevard north and connect to the freeway using Skirball Center Drive. For southbound traffic, the suggested route is to take Sepulveda Boulevard south and then use Church Lane to reach the Sunset Boulevard on-ramp.
Impact on Local Residents
Residents and businesses in proximity to the construction zone may experience temporary disturbances, including noise, vibrations, and dust as crews conduct the necessary work. Caltrans has advised commuters to check real-time traffic updates via the Caltrans QuickMap website to stay informed about any changes to the construction schedule.
Official Statements
Caltrans officials have emphasized the importance of these upgrades, stating that the project is crucial for improving safety and mobility along the I-405 corridor. They have also warned that significant traffic delays are expected during the construction period, urging drivers to plan ahead.
