Commuters should plan for another round of overnight closures on the 405 Freeway this weekend.
The northbound 405 Freeway from Getty Center Drive to Ventura Boulevard will be closed Saturday night.
Lane closures are going into effect at 10 p.m., with some ramps shutting down as early as 7 p.m., according to Caltrans.

Sepulveda Boulevard will remain open as an alternate route.
The work is part of the Sepulveda Pass Improvements Project, a $1.2 billion effort to add a 10-mile carpool lane and improve ramps, bridges and sound walls, according to Los Angeles County Metropolitan Transportation Authority.
Some drivers are resigned to the inconvenience. They've been dealing with congested on-ramps, a diverted Sepulveda Boulevard, and confusing late night closures for more than a year already.
"If you try to take the side streets, you're gonna get the same thing," said motorist Robert Martinez. "It's terrible."
But MTA officials say all the work will be worth it when the carpool lane project is done.
"I think the net effect of traffic will be, improved mobility with the addition of the carpool lane," said Dave Sotero, spokesman for the MTA.
