the Dover Downs harness racing track adjacent to the Dover speedway. Dover Motorsports also operated Nashville Superspeedway, a 1.333-mile concrete oval track in Lebanon, Tennessee. Dover Motorsports owned Memphis Motorsports Park, a 0.75-mile tri-oval asphalt short track in Millington, Tennessee, but closed the track in October 2009 to competition. It was later sold to Palm Beach International Raceway after sitting unused for over a year. Dover also owned Gateway International Raceway, a 1.25-mile egg-shaped asphalt oval track in Madison, Illinois, which was sold in 2011. After attempts to sale Nashville Superspeedway, the venue reopened in 2021 and hosted a NASCAR race weekend, replacing one of the race weekends at Dover International Speedway. On November 8, 2021, Speedway Motorsports announced that it had agreed to purchase Dover Motorsports, owner of Dover International Speedway and Nashville Superspeedway at the time, for $3.61 per share in cash for an approximate total equity value of $131.5 million. The deal closed in December, with SMI gaining full control of the two tracks. Principal subsidiaries Tracks Atlanta Motor Speedway, Inc. Bristol Motor Speedway, Inc. Charlotte Motor Speedway, Inc.
