 A water line break caused a large sinkhole Friday night, and the closure this weekend of a major road in Pleasant Hill.

Just after 9 p.m. Friday, Pleasant Hill Police received reports of flooding in the area of Contra Costa Boulevard
between Woodsworth and Gregory lanes.

 A water line apparently ruptured, beneath the roadway surface of the southbound lanes, and caused water to escape through the cracks in the street.

It flooded the roadway and nearby businesses, police said.

The water flow also caused a large sinkhole to develop.

Crews were able to shut off the water overnight.

Contra Costa Water District went to the scene to begin repairs, which are expected to take 24 hours.

The roadway will likely remain closed through Sunday.
