Lime Rock Park | 1,190 followers on LinkedIn. Motorsports park located between New York City and Boston among the hills and countryside of Northwest Connecticut. | It can be easily argued that Connecticut’s Lime Rock Park is the most significantly historic road racing circuit in North America. Only Wisconsin’s Road America and California’s Laguna Seca can compare to Lime Rock with respect to longest continuous operation – Road America opened in 1955, Laguna Seca and Lime Rock in 1957 – but only Lime Rock’s circuit remains exactly the same as when it opened in spring of that year. Lime Rock is 1.50 miles of up hill and down dale, a track that looks deceivingly simple but is immensely challenging to drive quickly.
