The 405 Freeway is closed in both directions between Venice Boulevard and the 10 Freeway after a CHP officer was involved in a crash.

The motorcycle officer was taken to a nearby hospital in critical condition after the 8:35 a.m. crash Wednesday on the northbound 405 Freeway near National Boulevard, said CHP spokesman Francisco Villalobos.

The cause of the crash was under investigation.

“We're kind of sketchy right now,” Villalobos said. “That freeway is going to be closed off for quite a while while we do the investigation.”

He estimated the freeway would be closed for one to two hours while investigators work the scene.
