A large water main break in West Hollywood floods parts of the neighborhood off Sunset Boulevard, disrupting traffic and damaging streets. Multiple outlets report that the century-old pipe bursts underground early Thursday, sending water spewing onto nearby roads and submerging vehicles. In footage and descriptions of the aftermath, water covers portions of Sunset Boulevard and surrounding streets, with at least some cars and transit vehicles reported as partially submerged in brown, muddy water. The rupture also leaves a sinkhole and cracked pavement at the site. Local officials indicate the affected line is about 100 years old and could require significant time to repair. As crews respond, authorities shut down or reduce access to several major roads in the area, including routes around Sunset Boulevard and nearby streets such as Holloway Drive, affecting businesses and daily activity. While the cause of the break is not detailed in the reports, the incident centers on the failure of the aged pipe, which causes widespread flooding and infrastructure damage until repairs are completed.
