405 Freeway Closures To Snarl Traffic In LA County Beginning Friday, July 24

LOS ANGELES, CA — Traffic will be impacted on the 405 Freeway and nearby roads July 24-27 when construction will shut down several lanes and ramps of the interstate in the San Fernando Valley for the entire weekend.

Here's a look at the closures, planned for 10 p.m. Friday, July 24 through 5 a.m. Monday, July 27:

Southbound 405

• The southbound 405 Freeway will be reduced to two lanes in the area of the 101 Freeway in Sherman Oaks
• The Burbank Boulevard on-ramp to the southbound 405 will be closed

Northbound 405

• The northbound 405 off-ramp to Getty Center Drive will be closed

101 Freeway

• The northbound 101 connector to the southbound 405 will be closed

Officials urged drivers to consider the following alternate route:

Northbound 101 to southbound 405: Exit at Sepulveda Boulevard and head south on Sepulveda Boulevard to the Sepulveda Boulevard on-ramp to the southbound 405.

Construction has been underway on the 405 Freeway in and near the Sepulveda Pass since June 2025 as part of the I-405 Pavement Rehabilitation Project, a $143.7 million project to improve safety and mobility along the freeway and extend the life of its pavement, according to Caltrans.

Many of the associated road closures occur overnight. But big traffic headaches have come courtesy of what Caltrans calls Extended Weekend Closures — that's when crews shut down lanes and/or ramps on Friday night and keep them closed until Monday morning.

Those weekend-long closures will happen at a pace of about every other week — or twice a month.

Caltrans does not have a finalized schedule for each weekend-long closure, but said there will be about 25 total weekend-long closures.
