Work crews are prepping the Skydome at the National Corvette Museum in Bowling Green for reopening in July.
Construction began last November in an area where eight prized cars fell into a massive sinkhole in February 2014.
The hole was filled with crushed limestone and flooring supports were added underneath to prevent future collapses.
"If there were ever a future collapse of any kind, the floor is not going to go anywhere, it will stay in place," says NCM Marketing and Communications Director Katie Frassinelli. "After that, they've been installing guardrail around the perimeter of room, cleaning, and painting."
The $5 million project converted the Skydome from two levels to one and added more display space.
Once complete, all eight Corvettes will return to the Skydome. Three of the cars were restored by General Motors. The other five were too mangled for restoration.
A new sinkhole exhibit will open in the fall.
