Dozens of residents remain without vehicle access to their homes a day after a water main ruptured in Chino Hills.
The 16-inch water main burst around noon Sunday in the 1700 block of Rancho Hills Road.
A river of water was sent onto the street above, where sections of the roadway had crumbled and buckled by Monday morning.
Officials are even more concerned about the amount of water flowing beneath the street, which officials initially believed had compromised a 2,000- to 3,000-foot section of Rancho Hills Drive, the Chino Valley Fire District posted on its Facebook page Sunday.
The amount of roadway that will need to be repaired was later reduced to about 1,200 feet.
Area residents were asked to shelter in place Sunday until crews got the water turned off.
Rancho Hills Road was closed up to the intersection of Ranch Creek Lane, the Fire District stated.
It’s not clear when the road will reopen.
