It was a disaster turned into a tourist attraction.

Bowling Green gained worldwide attention when a sinkhole swallowed eight cars at the National Corvette Museum back in 2014.

While no other sinkholes have earned that level of fame, it's a common problem in a city that just sits 40 miles from Mammoth Cave.

The city has hired a professional geologist to oversee sinkhole repairs and help prevent further destruction.

Our Laura Rogers joined him on a recent project that.

Could be just about anywhere in town, any given minute.

That's certainly the case when you are a professional geologist in a city well accustomed to sinkholes.

Sinkholes are about 50% of my time today.

Nick Line is overseeing a project and the Briarwood neighborhood of Bowling Green.

We will analyze pretty much every bucket of dirt that comes out of here looking to see, are we digging in the right place?

Have we dug deep enough that we can start to backfill with rock and replace the unstable soil material?

What was originally a 12 foot sinkhole is now 40 feet deep.

As crews dig out the unstable soil down to the bedrock.

This one here has been rather more difficult, a large excavation.

Page says.

This site has been more challenging because utilities have been in the way.

We've had a water line, gas line, fiber optics and the sinkholes directly underneath them.

Sinkholes can be a problem for infrastructure and commercial development.

It presents design challenges for engineering firms.

It presents management challenges for anybody building anything.

As a city geologist, Nick Laughlin looks at development plans working to identify any potential issues like sinkholes or cave systems that may pose a risk.

Just about anywhere where you get limestone or dolomite close to the surface, you're going to have concerns with sinkholes.

You're going to have concerns with a very fragile groundwater system that can be easily polluted.

Home to Mammoth Cave National Park, Kentucky, is believed to have more than 10,000 caves.

It's just such a big cavern system in Bowling Green.

They're sinkholes everywhere.

They form when rainwater seeps through cracks in the limestone.

Sinkholes are the points at which that water gets down into the ground.

This neighborhood is familiar with the disruption.

The sinkhole sits about 50 feet from another one that opened up back in September.

It's louder than normal when you have equipment running.

We had dump trucks coming in and out.

People are having to find other ways around changing their routes to school.

Mail carrier has to go around and add a couple of quarters of a mile to his route, that kind of thing.

The crew is currently flushing water into the sinkhole to see how it drains.

They expect the project to be completed sometime next week.

For Kentucky Edition, I'm Laura Rogers.

Thank you, Laura.

The city geologist says sinkholes can collapse over time or be triggered by weather, such as a lot of rain after a dry period or from vibrations due to new construction.
