Portions of the Golden State Freeway (Interstate 5) between the Hollywood Freeway (State Route 170) and the Kern County line will be closed at night on Wednesday through early Saturday, the California Department of Transportation has announced.

The closures are part of a sign replacement project.

Caltrans said the following schedule will be in effect, weather permitting, and is subject to change:

Wednesday, Dec. 28, through early Saturday, Dec. 31

Northbound I-5

Southbound I-5

The nighttime closures are necessary to minimize traffic delays and provide a safe work zone for construction crews, a Caltrans statement said.

"Construction signs and changeable message signs will be in place to alert motorists of closures," Caltrans said. "Motorists should anticipate delays, plan ahead and use alternate routes."

The work is part of a $2.5 million project that began in June and is expected to be completed by summer.

The contractor for the project, Statewide Traffic Safety and Signs, Inc., is bringing existing signs and their structures to current standards, Caltrans said.
