Overview
- More than 100 LAFD responders including confined-space specialists entered the 450-foot-deep tunnel after a section gave way miles from its sole access shaft.
- Video footage showed workers securing themselves inside a yellow rescue cage that was lifted by crane in multiple trips after communication lines were severed.
- Mayor Karen Bass provided on-site briefings as paramedics assessed all personnel and confirmed that none of the 31 rescued workers suffered injuries.
- The collapse occurred at the $630.5 million Los Angeles Effluent Outfall Tunnel project, a key wastewater upgrade whose tunneling phase is due for completion this year.
- County sanitation engineers and city inspectors have begun analyzing soil conditions and support structures to determine the cause of the partial collapse.
