Two people were killed in a multi-vehicle crash in the Glendora area on Wednesday morning, resulting in an hourslong closure of all westbound lanes on the 210 Freeway at the 57 Freeway, according to the California Highway Patrol.

Two westbound lanes were reopened as of 12:30 p.m., as was the entire eastbound side of the freeway, CHP Officer Monica Posada said. All lanes were reopened by about 2 p.m.

Emergency personnel responded to the crash site about 9:40 a.m., according to the Highway Patrol's incident log.

The one person was initially trapped in one of the three vehicles involved in the collision, said Supervisor Melanie Flores of the Los Angeles County Fire Department.

Sky5 video showed a patient on a gurney being loaded into a Fire Department helicopter that landed on the freeway. Posada confirmed one person was airlifted from the scene.

The cause of the crash was unknown.

Correction: The rescue helicopter was misidentified in an earlier version of this story. It has been corrected.
