LOUISVILLE, Ky. (WDRB) -- Work continues at the site of the sinkhole inside the National Corvette Museum.

Crews are working to stabilize the exterior of the skydome building and remove concrete that is currently hanging over the sinkhole, that initially swallowed 8 cars.

Three corvettes are still inside the sinkhole.

"After they remove the corvettes they're going to work on going in and checking out what's going on under the surface and taking care of any cave issues and filling the sinkhole back up and making the sinkhole good as new," says Katie Frassinelli, Marketing and Communications Manager for the Corvette Museum.

By August, they hope to reopen the skydome area.

In the meantime, tourists are getting a look at the process through a viewing window.

"We were interested in looking at the sinkhole," says Kelly Nicholson, a Tennessee resident.

"It's kind of a one in a lifetime event," says Glen Acre, an Arkansas resident. It's something many of them say they have to see.

"This is pretty dramatic. Television and pictures don't do justice to how much damage there was to the cars," says Glen Acre.

Museum officials say they've noticed a 20 percent increase in tourism since the sinkhole developed.

Most of the damaged cars will be restored if possible, but at least one may be saved for permanent display.

"We'll talk about if there's one we want to leave as is to kind of tell this story, as it is a piece of corvette history," says Katie Frassinelli.

Museum officials say they hope to have the last 3 corvettes out of the sinkhole by mid to late April, and then visitor's will have a chance to check them out through the end of August.
