A Rapid City street is closed until Monday following a large water main break.
Saint Patrick Street ... West of Mount Rushmore Road is under repair after a Black Hills Power crew ruptured a PVC pipe while installing underground power lines.
Rapid City Water Superintendent, John Wagner says the pipe burst caused an estimated half a million gallons of water to flow into the street and eventually the storm drains.
Wagner says the pipe likely split and will have to be replaced. That will require a large excavation hole ... And time.
Three or four customers were without water service due to the break.
