The official enquiry into the 1955 Le Mans disaster found severe deficiencies in the track layout along the main straight and for quite some time there were serious concerns for the future of the race. However, the ACO took all the recommendations on board and was able to convince the French government for continuation. The extensive renovations cost FF300 million, moving 70000 cubic metres of earth and meant the race was delayed 7 weeks to the end of July.
