The third oldest continuously operating road circuit in America, Lime Rock Park opened in 1957 and has effectively had the same main layout ever since.

Previously owned by Skip Barber, who started his eponymous racing school at the track, the circuit is noted for continuing to host top sportscar races, despite a ban on Sunday racing restricting its availability.

The circuit was founded by Jim Vaill, whose father owned the land on which the circuit now sits. Vaill and friend Jack Fisher would often race cars in the fields in the area, so they worked with John Fitch to design a permanent circuit, following discussions with the Sports Car Club of America.

Despite Sunday racing being prohibited since 1963, the circuit was successful in its early years. In 1985 Barber purchased the circuit, and the circuit has since been resurfaced twice – in 1992 and 2008. The latter year also saw the addition of two optional sections of track – a slower uphill section, and a new alternative chicane at the westernmost bend.

The circuit changed hands again in 2021, with Lime Rock Park LLC acquiring the venue. The organisation was formed specifically for the acquisition of the circuit, with Barber remaining involved in the running of the track.
