A massive water main break early Thursday morning flooded several blocks of West Hollywood, turning streets into rivers and damaging property in one of Los Angeles' most trafficked areas. The rupture occurred around 3 a.m. near the intersection of Sunset Boulevard and Holloway Drive, sending thousands of gallons of water into apartment complexes, underground parking garages, and nearby businesses [1][2].
The broken pipe was a 36-inch riveted steel trunk line installed in 1916, making it 110 years old and a critical artery in the city's water delivery system [3][8]. While the exact cause of the fracture remains under investigation, officials suspect high nighttime water pressure on the aging, corroded pipe may have triggered the rupture [3][7]. The incident created a large sinkhole on Sunset Boulevard and forced the closure of Eastbound Sunset, Santa Monica, and Holloway Drive, causing severe traffic gridlock and diverting Metro bus routes [1][7].
LA Mayor Karen Bass called the break a "representative problem" of aging infrastructure during a现场 press conference, emphasizing the urgent need to modernize the city's underground systems [source from Korean text, not in search results but consistent with public statements]. The Los Angeles Department of Water and Power (LADWP) confirmed that water service was restored to nearly all affected customers by 9 a.m., with only one customer temporarily without service [3][4]. No injuries were reported, and while an evacuation zone was established as a precaution, no residents were forced to leave their homes [3][7].
This incident highlights Los Angeles' long-standing struggle with deteriorating infrastructure, as approximately 30 percent of the city's 547 miles of major water lines are more than 80 years old [source from Korean text]. UC Irvine professor David Feldman noted that while replacing all aging pipes is financially and practically impossible, targeted replacements are critical to prevent future disasters [source from Korean text]. LADWP officials stated there is currently no timeline for full repairs to the buckled roadways and collapsed sidewalks [1][7
