The sale closed Dec. 31, Concord,-based SMI (NYSE:TRK) says.

The 1.5-mile track, located between Louisville and Cincinnati, opened in 2000. It has 66,000 grandstand seats and 50 luxury seats.

For years, former track owner Jerry Carroll unsuccessfully lobbied NASCAR for a race featuring its top division, the NASCAR Sprint Cup Series. Bruton Smith, SMI chairman, says he will continue to fight for a Sprint Cup date at the track.

“We are going to do everything we can to bring the great people of Kentucky what they want and deserve,” Smith says in a press release.

Kentucky Speedway holds a NASCAR Nationwide Series race, a NASCAR Camping World Truck Series race, two ARCA RE/MAX Series races and an IndyCar Series Race. Many NASCAR Sprint Cup Series teams also have used Kentucky Speedway in the past for testing cars before races at tracks with similar distances and characteristics.

SMI also owns and operates Atlanta Motor Speedway; Bristol Motor Speedway in Bristol, Tenn.; Infineon Raceway in Sonoma, Calif.; Las Vegas Motor Speedway; Lowe’s Motor Speedway in Concord; New Hampshire Motor Speedway in Loudon, N.H.; and Texas Motor Speedway in Fort Worth, Texas.
