A major water main rupture in West Hollywood caused a massive sinkhole and flooded neighborhoods, damaging over 150 vehicles and requiring extensive repairs.The 100-year-old pipe, which burst on July 16, released 17 million gallons of water, submerging parked cars and apartment complexes.

The Los Angeles Department of Water and Power (LADWP) reported significant progress in repairing the 3-foot-wide trunk line, replacing a 25-foot section with a new steel pipe.Welding and pressure testing are underway, with crews working to disinfect the water line and restore service.Sunset Boulevard remains closed to traffic, though the closure area has been reduced to a section between Sherbourne Drive and San Vicente Boulevard.Residents are advised to conserve water until repairs are complete, relying on a temporary 8-inch pipe.The LADWP has not provided an estimated completion date, and traffic resumption remains uncertain.

Officials are also assisting residents with claims for water damage, including those affected by compromised electrical panels in underground garages.
