A burst water pipe created a mess along a road in Valley Center, ultimately causing a sinkhole on the shoulder.
Water flooded the side of eastbound Paradise Mountain Road beginning just before 6 a.m. Friday.
Service was shut off for a few dozen residents until Friday evening while crews correct the issue.
The sinkhole was estimated to be 20 feet wide. Traffic was still flowing in the area but traffic cones warned drivers of the sinkhole.
The break may have been caused by a previous repair done improperly, according to Valley Center Municipal Water General Manager Gary T. Arant.
He added that the pipe that broke was old itself.
To help customers who have been asked to limit their use until the lines can be re-pressurized, the agency is distributing bottled water and providing a water truck for those with livestock.
