One person was killed early Sunday morning in a crash on the 210 Freeway in Arcadia.
The crash happened just before 3:30 a.m. on the eastbound side of the 210 Freeway at Santa Anita Avenue.
Multiple vehicles were involved in the crash, including a semi truck, the California Highway Patrol said.
Video from the scene showed what appeared to be a black sedan that had flipped onto its roof.
The crash led to a shutdown of all lanes around 4 a.m. By 5:15 a.m., the far left lane was reopened and traffic was moving slowly through the crash site.
The crash is under investigation by CHP.
