One lane connecting the southbound 605 and westbound 105 freeways was closed, before a Sigalert was issued for all southbound lanes. The freeway was reopened by 7:15 a.m.

According to the California Highway Patrol Santa Fe Springs division, the driver was unaware the cage of chickens fell off his truck and did not stop.
