LOUISVILLE, Ky. (WHAS11) – The damage is severe and the impact far-reaching, after a water main break in the Shelby Park neighborhood.

Downtown businesses had to shut down for the day without water at the buildings and two hospitals canceled elective surgeries.

Those who live nearby had to deal with partially submerged vehicles, flooded yards and flooded streets for much of the day.

"I look outside and it’s a river- just a raging, wide, brown river,” Janet Weeden said.

Weeden had a front seat view of one of the most major water main breaks in Louisville's recent history. She lives on Oak Street, a few doors down from where the water main break happened.

"This one's pretty bad,” Louisville Fire’s Salvador Melendez said.

It was reported early Tuesday morning and wasn't completely shut down for nearly nine hours- allowing water to wash over several blocks of Shelby Park."You could not see the roads,” Marisa McClintock said.

Cars were partially submerged and some drivers were trapped. A JCPS bus driver and passenger van rescued by firefighters.Melendez explained, "Several other passengers that were not in danger immediately at that moment were guided into safety by our crews."

The pipe affected is one of the oldest and largest in Louisville.

Water company officials said they won't know what caused the water main break until they have a chance to get in and look at it.

Until then, they are focused on clean up. MSD workers are bulldozing mud, Water Company officials are working on pipes and Public Works employees ready to salt the streets as soon as they can.

NOTE: The American Red Cross has opened a shelter for those affected by the Shelby Park water main break. That facility is located at Sojourn Community Church and the address is 1303 South Shelby Street. This is to give residents a safe place to stay.
