LOS ANGELES, CALIFORNIA — Major traffic disruptions are ongoing this weekend along the 405 Freeway as Caltrans reduces lanes and closes ramps between April 10 and April 13 as part of a $143 million pavement rehabilitation project, with significant delays expected for anyone traveling between west Los Angeles and the San Fernando Valley during the closure period.
Caltrans Reducing Lanes and Closing Ramps Along the 405 This Weekend
The California Department of Transportation has moved forward with planned lane reductions and ramp closures along one of the busiest freeway corridors in the country. The work is part of a large-scale pavement rehabilitation effort valued at $143 million, targeting sections of the 405 that connect west Los Angeles to the Valley.
The closures are not a brief overnight operation. They span the entire weekend window from April 10 through April 13, meaning drivers who regularly rely on this stretch of the freeway will need to account for significantly altered travel conditions for multiple consecutive days.
$143 Million Pavement Rehabilitation Project Driving the Weekend Shutdown
The scale of this weekend’s disruption is directly tied to the size and scope of the rehabilitation project underway. At $143 million, the pavement work represents a substantial infrastructure investment aimed at improving road conditions along one of Southern California’s most heavily trafficked corridors.
Projects of this nature typically require extended lane and ramp access restrictions to allow crews to work safely and efficiently. The April 10 through 13 window was selected to concentrate the disruption over a weekend period, though travel demand along the 405 remains high even on Saturdays and Sundays given the volume of commuters and recreational travelers using the route.
West Los Angeles to Valley Corridor Facing Heaviest Impact
The stretch of the 405 connecting west Los Angeles and the San Fernando Valley is among the most congested in the United States under normal conditions. With lanes reduced and ramps closed throughout this weekend, drivers traveling in either direction between these two areas are facing considerably longer travel times.
Motorists are strongly advised to plan ahead, check real-time traffic conditions before departing, and consider alternate routes where possible. Those with flexible schedules may benefit from adjusting travel times to avoid the heaviest periods of congestion expected during the closure window.
Closures Running Through April 13 With Delays Developing Across the Region
The lane and ramp restrictions are developing and ongoing through the end of the closure window on April 13. As the weekend progresses, traffic conditions along surrounding surface streets and alternate freeway routes may also be affected as drivers divert away from the impacted 405 corridor.
Travelers heading to or from the Westside, the Valley, and connecting areas should monitor official Caltrans updates and local traffic advisories for the latest information on lane availability and ramp access as the project work continues.
