Lime Rock Park is a 1.53 (1.54 with the chicane) mile road course locatedin Lime Rock, Connecticut, in the extreme Northwestern corner of the state.There is a Kart Track at the top of the hill which is often used for Kart racing events.The track is located on CT Route 112, just east of Millerton, New York and south of Lakeville, CT.

Finally, the East Coast headquarters of the SkipBarber Racing School is located nearby in Lakeville, and Lime Rock is oneof the most popular sites for Barber schools and races.

Lime Rock Park was built in the mid to late 1950s by Jim Vaill, on the siteof a cornfield/gravel pit on land owned by his father. Vaill's friend JackFisher owned an MG-TC, and they often drove it rapidly in circles in thecornfield at the top of the hill; in real life Vaill operated the gravelpit that was on the site, in the north face of the hill (the gravel pit waslocated roughly where the A Paddock restrooms and the Driving Impressionsstore are now located.)

Vaill's original plans were for both the short circuit that we know today,and an extended 3 mile long "Mountain Circuit", which would have used thehill east of the track. The trees were bulldozed for the mountain circuit,but it was never built. The path of the "Mountain Circuit" may be tracedtoday on foot by the intrepid.

Lime Rock Park opened in 1957, and has hosted a remarkable variety of racesover the years, including most of the various IMSA series,American LeMans Series, most of the variousSCCA series, and the NASCARBusch North Series. The facility is too small to support Indycar,Formula One, or NASCAR Nextel Cup. In recent years Lime Rock has repavedthe entire track, widened the pit lane, significantly improved the restrooms,and paved the roadways through the paddock.

Lime Rock is not beloved by all the residents of the area. Since 1963, LimeRock has operated under the terms of a consent decree that limits the noiselevels and operating hours of the track. As a result, there is never anySunday racing at the track; unmuffled dates are restricted to a specificnumber of Fridays, Saturdays, and Holidays; and operation of race enginesis limited to a specific range of hours of the day (which varies accordingto the rather complex terms of the consent decree.)
