Crews are actively working on repairs following a significant rupture of a 100-year-old water main in West Hollywood. The incident led to the formation of a sinkhole and subsequent flooding in the area.
The repair process has involved the replacement of a 25-foot section of the aging water main. While officials report that progress is being made on the necessary repairs, a specific timeline for the full completion of the work has not yet been provided.
As a result of the ongoing repairs and the initial incident, a significant portion of Sunset Boulevard remains closed.
