Rescue Operation Saves Over 30 Workers from Tunnel Collapse in LA

More than 30 individuals who were laboring in an 18-foot wastewater tunnel in Los Angeles were successfully saved after the tunnel's collapse occurred on Wednesday night.

According to a statement released by the Los Angeles Fire Department on Wednesday evening, the incident took place at an excavation site underground, positioned between five to six miles from the tunnel's only access point.

This tunnel was being developed for the purpose of municipal wastewater infrastructure, as mentioned by the fire department.

The workers who were trapped within managed to climb with considerable effort over a large heap of earth, subsequently reuniting with fellow workers beyond the debris. They then traveled over five miles back to the tunnel entrance using a vehicle designed for tunnel transport, according to the fire department's details.

Los Angeles' Mayor, Karen Bass, communicated via an X social media post on Wednesday that all workers situated in the Wilmington tunnel had been successfully extracted and are accounted for.

"I had the opportunity to talk with many of the workers who were trapped. Immense gratitude to our courageous first responders for their immediate action. You represent the true spirit of LA's heroes," wrote Bass on X.

Earlier, Bass had conveyed through X that in excess of 100 personnel from the Los Angeles Fire Department were dispatched to conduct the rescue operation.

Rescue Operation Details

Michael Chee, acting as a spokesperson for the Los Angeles County Sanitation District, indicated to the Los Angeles Times on Wednesday that workers were extricated from the tunnel shaft in groups of eight using an apparatus known as a bird cage.

This tunnel construction was part of a substantial $630.5 million contract granted in January 2019 to Dragados USA, a company renowned for its extensive tunneling experience in significant construction endeavors.

The Los Angeles County Sanitation District, along with ACS Group, the company overseeing Dragados USA, did not rapidly offer comments when approached by Business Insider.
