1932 Le Mans, Les 24 heures du Mans – This race saw the shortening of the circuit to nearly 13.5 km following the creation of a new permanent race track between the pit stretch and Mulsanne, creating the famed Dunlop Curve, Esses, and Tetre Rouge. This change was made to keep the race out of the suburbs of Le Mans.  The two Dunlop Bridges were also first seen at this race.
