A water main break on Sunset Boulevard near the University of California, Los Angeles resulted in extensive flooding on parts of the school’s campus Tuesday.

“It’s like a bomb went off,” a KABC-TV anchor said, describing the images from the scene of the water main break.

The rupture happened around 3:30 p.m. Footage from the scene showed water gushing from the pipe, forcing the surrounding asphalt to collapse. Roughly four hours later, the water flow was eventually shut off. Officials estimate millions of gallons had ultimately poured into the surrounding area.

Students were told to avoid the affected locations. UCLA said the school is assessing the damage.

The Los Angeles Department of Water and Power said the damaged pipe was a 30-inch, 90-year-old riveted steel pipe delivering water from the Upper Stone Canyon Reservoir.
