The sinkhole that swallowed up eight cars at the National Corvette Museum in Bowling Green, Kent., in February quickly became one a favorite exhibit, but that’s not enough to head off a decision to till in the 60-foot wide, 40-foot-deep orifice in the floor.

Reuters reports:

“The board had voted in June to attempt to keep part of the hole open, but the cost of retaining walls and other construction would exceed $1 million, officials at the museum in Bowling Green, Kentucky, said in a statement.

“‘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,’ museum executive director Wendell Strode said in the statement. ‘But after receiving more detailed pricing, the cost outweighs the benefit.'”

As we reported after the Feb. 12 incident, which was witnessed by security cameras, the floor suddenly opened up and consumed six Corvettes owned by the museum, ranging in vintage from 1962 to 2009 and two GM ZR-1s on loan from General Motors.
