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.
And it was Lime Rock Park that hosted the race that forever changed the face of motorsports in America, the 1959 Formula Libre event. The best pros and the best amateurs in the best cars went head-to-head in a three-heat format. Thanks in equal part to its major media coverage and the fact that Indy 500 winner Roger Ward won the contest – in a midget – the Formula Libre weekend knocked down the walls that had separated professional road racing drivers from their amateur brethren.
