For years the track was listed as being 1.53 miles in length—the story goes that right after it was built, somebody used the odometer in a Chevy to measure the track length—and 1.53 was taken as gospel. Following the 2008 reconstruction (see below), Lime Rock's operations people measured all four possible configurations, and as it turns out, each was 1.5-miles long, plus or minus a few hundred feet. The "classic" configuration is 7 turns, while the three optional layouts are 8, 9 and 10 turns, respectively.
Two years after the park first opened in 1957 the Lime Rock Protective Association, with support from the nearby Trinity Episcopal Church, took the park to Litchfield Superior Court in an effort to ban Sunday racing. The court issued a permanent injunction against Sunday racing and its decision was upheld by the Connecticut Supreme Court. Although park officials have expressed a desire to return to limited Sunday racing, the injunction stands to this day.
