LOS ANGELES, CA — Traffic will be impacted on the 405 Freeway and nearby roads this weekend when construction will shut down several lanes and ramps of the interstate in the San Fernando Valley beginning Friday.

Northbound 405 Freeway

The southbound freeway will not be impacted by the closure.

Officials urged drivers to consider the following alternate routes:

Northbound 101 to northbound 405: Exit at Sepulveda Boulevard and head north on Sepulveda Boulevard, then west on Victory Boulevard to the northbound 405 on-ramp.

Southbound 101 to northbound 405: Travel southbound on the 405 and exit at Ventura Boulevard. Head east on Ventura, south on Dickens Street, south on Sepulveda Boulevard to the northbound 405 on-ramp.

Construction has been underway on the 405 Freeway in and near the Sepulveda Pass since June 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.
