A section of a large industrial tunnel collapsed beneath the Wilmington neighborhood of Los Angeles, trapping 31 construction workers approximately 400 feet underground and up to six miles from the only exit. Remarkably, all workers escaped safely without major injuries.
The incident occurred around 8 p.m. in the 1700 block of North Figueroa Street. The workers were engaged in the construction of an 18-foot diameter tunnel designed to carry treated wastewater to the Pacific Ocean. This $700 million project had been underway for two years without prior incidents.
Upon realizing the collapse, the workers initially attempted to return to the tunnel’s entrance using a transport vehicle. However, the vehicle was halted about a mile from the collapse due to debris. Undeterred, the workers navigated the remaining distance on foot in complete darkness, climbing over a 12 to 15-foot mound of loose soil to reach coworkers on the other side of the collapse. They were then shuttled, several at a time, by tunnel vehicle to the entry point.
Los Angeles Fire Department Chief Ronnie Villanueva praised the workers’ composure during the crisis. “Tonight, we were lucky,” he said. “It was determined that a structure failure of the tunnel lining failed approximately five to six miles in.”
Los Angeles Mayor Karen Bass also commended the workers and first responders. “We’re all blessed today in Los Angeles. No one injured. Everyone safe,” she stated. “I just spoke with many of the workers who were trapped. Thank you to all of our brave first responders who acted immediately. You are L.A.’s true heroes.”
The tunnel, part of the Clearwater Project, is expected to be completed and active by 2028. Following the collapse, work on the site has been halted, and an investigation into the cause is underway. Given the complexity and depth of the site, officials anticipate that the investigation could take several months.
Structural engineers have noted that working near the shoreline and at such depths presents unique challenges, including dealing with wet conditions that can affect tunnel design and construction. Maria Mohammed, president of the Structural Engineers Association of Southern California, emphasized the need for a thorough assessment to determine the cause of the collapse.
Local officials have praised the workers’ composure and the emergency response during the crisis. City Councilmember Tim McOsker highlighted the technical difficulty of the project and the workers’ ability to secure themselves. “Thank goodness for the good people that were down in the tunnel,” he said.
The incident serves as a stark reminder of the inherent risks associated with large-scale infrastructure projects, particularly those involving complex underground work. The swift and coordinated response by the Los Angeles Fire Department and the workers’ quick thinking were instrumental in preventing what could have been a tragic outcome.
