LOS ANGELES (AP) — A parade of tow trucks on Friday brought hundreds of cars up from two underground garages at the University of California, Los Angeles, that flooded when 20 million gallons of water spewed from a broken main.

Crews were removing about 400 vehicles that were submerged in Tuesday's deluge, UCLA spokesman Tod Tamberg said. The process could take several days because workers were still pumping out water and digging through muck and debris, he said.

About 270 cars not damaged by water were removed earlier, and their owners began retrieving them Friday.

UCLA officials said six facilities were damaged in the flooding. Two of them — the Arthur Ashe Student Health and Wellness Center and the Drake Track and Field Stadium — were reopened Thursday, Tamberg said.

On nearby Sunset Boulevard, Los Angeles Department of Water and Power crews were cutting out pieces of the broken century-old steel line.

Workers off-site were fashioning a Y-shaped connector to replace the section that burst where two trunk lines merge.

Department of Water and Power officials said the pipe-replacement work would likely begin Friday afternoon or evening. When that's finished, work could begin on repairing the famed boulevard, a heavily traveled east-west thoroughfare, pushing reopening well into the weekend.
