Originally built in 1952 by Eugene Chaney a large Maryland-based sand, gravel and concrete producer, Marlboro started life as an all-dirt oval track. For the 1954 season, a road course was added, and the oval track was paved and incorporated into the twisty 1.7-mile road course, making it a favorite racetrack for SCCA racing. The development of this road course was heavily influenced by the Lavender Hill Mob, a Washington, D.C.-based affiliate of the SCCA.
Marlboro played host to many high-profile motorsports events and welcomed many historic figures in automobile racing. Marlboro’s fate was sealed primarily by the construction of Summit Point Speedway not far away. The major safety concern at Marlboro were the two opposing straights of the circuit. Oncoming traffic was mostly separated by nothing more than a grass median. The BARCboys went to Marlboro for over a decade, both as crew and driving. Marlboro Raceway closed in 1970 after 40 years of racing.
