A massive sinkhole that swallowed eight prized sports cars won't be a permanent attraction at the National Corvette Museum in Kentucky.
The museum's board of directors voted Saturday to fill in the entire hole that opened up in February and became an Internet sensation. Curiosity over the hole revved up attendance and revenue for the museum in Bowling Green.
Board members reversed course by deciding against preserving a section of the gaping hole.
Mindful of the hole's popularity, museum officials in late June were leaning toward keeping part of the hole open and putting a crumpled sports car back in it to memorialize what happened when cars toppled like toys amid rocks, concrete and dirt when the sinkhole opened up in the museum's Skydome.
The option of keeping part of the hole open lost favor because of added costs due to safety features, museum officials said.
"We really wanted to preserve a portion of the hole so that guests for years to come could see a little bit of what it was like, but after receiving more detailed pricing, the cost outweighs the benefit," said museum Executive Director Wendell Strode.
To keep part of the hole, workers would have installed 35-foot-tall retaining walls and inserted beams in the hole to prevent future cracking, said museum spokeswoman Katie Frassinelli. Costs mounted to about $1 million - double earlier estimates - due to safety and humidity-control features.
Another worry was ongoing maintenance costs if a section of the hole stayed open, they said.
"It just wasn't practical to do it," Strode said.
The museum didn't disclose how much it will cost to fill in the 60-foot-long, 45-foot-wide, 30-foot-deep sinkhole. Repairs are expected to start in November and take about six months, officials said. The museum will remain open, but the Skydome will be sealed off from visitors, who will be able to watch the repairs through a Plexiglas wall.
The hole will be filled completely with rock, then workers will drill into it to install steel casings, Frassinelli said.
