On February 12, 2014, a sinkhole opened under the floor of the Skydome area of the museum at around 5:44 AM local time, causing a portion of the floor to collapse. Kentucky is one of the many states that is notable for having karst topography. Karst topography is the landscape that is formed from the dissolving of rocks such as limestone. In the museum's case, the sinkhole was caused by the dissolving of the limestone in the ground which caused pockets to open underneath the surface. Eventually, the weight of the building caused the top layer of soil to collapse. Eight rare and one-of-a-kind Corvettes, portions of the display stands and rails, large concrete floor slabs and dirt fell into the sinkhole, causing serious damage to some of the Corvettes. The Corvettes involved have an estimated value of a million dollars.
After more than four months and 1,200 man-hours of painstaking craftsmanship, restoration of the milestone 1-millionth Corvette – a white 1992 convertible – is complete.
It was unveiled today at the National Corvette Museum, in Bowling Green, Ky., where it returns as part of the permanent exhibit. The car was damaged on Feb. 12, 2014, when it and seven other rare Corvettes tumbled into a sinkhole that opened beneath the museum’s Skydome area.
Chevrolet pledged to restore it.
After recovery from the sinkhole, the 1-millionth Corvette was moved from the museum to the Design Center on GM’s Technical Center campus in Warren, Mich., for restoration. Approximately 30 craftspeople and technicians from GM Design’s Mechanical Assembly group, along with GM Service Operations, took on the project. Mechanical Assembly and the Fabrication Shops at GM Design builds concept vehicles and maintains GM’s historic vehicle collection.
