110-Year-Old Pipe Bursts in West Hollywood, Opening Sinkhole on Sunset Boulevard

A 110-year-old riveted steel water main ruptured in West Hollywood on July 16, 2026, opening a sinkhole on Sunset Boulevard and flooding streets with murky brown water that partially submerged metro buses. No injuries were reported. Officials have not determined the cause or a repair timeline. The pipe predates West Hollywood's 1984 incorporation as a city.
