More than 30 people were rescued after a tunnel under construction collapsed in Wilmington on Wednesday night.

The 31 people, all presumed to be workers, were removed and are receiving medical assessments, but none of the survivors have visible injuries, said Brian Humphrey, a spokesperson for the Los Angeles Fire Department.

More than 100 firefighters responded around 8 p.m. near Figueroa Street and Lomita Boulevard, including members of the urban search and rescue team. By 9:15 p.m., all missing persons were removed, Humphrey said.

The tunnel, which measures 18 feet in diameter, was being constructed for municipal wastewater management and is a City of Los Angeles effort known as Clearwater Tunneling Project. It collapsed about five to six miles south of the tunnel’s only access point, Humphrey said.

Investigators believe some of the trapped workers pushed over a pile of loose soil between 12 feet and 15 feet tall to meet some of their co-workers on the other side and be shuttled several at a time to the access point.

Officials haven’t confirmed the depth or diameter of the collapse.

The City of Los Angeles has mobilized resources to the tunnel collapse in Wilmington.

More than 100 LAFD responders have been deployed, including Urban Search and Rescue teams.

Thank you to all of those who are acting immediately to respond to this emergency.
