SAN DIEGO (KGTV) - City crews worked through the night to repair a massive water main break that flooded streets and homes in North Park.
10News learned the cast-iron line that broke on Thursday morning was replaced with a PVC pipe on Friday, and crews were hard at work filling and repaving large hole that formed at the intersection of Idaho Street and Polk Avenue.
Because much of the street was left covered with dirt and mud, crews expected to remain there for road repaving and clean-up into Friday afternoon.

San Diego officials said a 90-year-old, 24-inch water transmission line broke on Idaho Street and Polk Avenue, near North Park Community Park, just after 7 a.m. Thursday.
The break caused the formation of a large hole in the road and sent water gushing throughout the neighborhood, leading officials to shut down several nearby streets.
The flowing water partially submerged several vehicles, caused damage to some homes and, in some cases, prevented some people from leaving their residences.
Students ALBA School, located on nearby Oregon Street, were told the leave campus as the main break led school district officials to close the school.

About three hours after the break occurred, city crews that were dispatched to the scene were able to shut off the flow of water.
Because the ruptured main was not linked to water meters, officials said customers in the area did not experience a loss in service. However, some reported low water pressure.
As a precaution, San Diego Gas & Electric crews turned off power to at least four apartment complexes near where the break occurred. Power was restored several hours later.
Affected streets were reopened later Thursday evening, but the site of the break -- Idaho Street at Polk Avenue remained closed as of 4:45 a.m. Friday.
The cause of the break remains under investigation, but officials believe age of the pipe may have led to the leak.
