The westbound lanes of the 101 Freeway in Agoura Hills were shut down Sunday morning following a crash involving a California Highway Patrol motorcycle officer, according to the CHP.

The officer was airlifted to a local hospital in unknown condition, according to the Los Angeles County Fire Department. 

The officer was on duty when he struck the center divider near Chesebro Road at around 7:30 a.m. A portion of the freeway was reopened about an hour later, but three lanes were expected to be closed until around 11:00 a.m., according to the CHP.
