Over the next year, the Automobile Club de l'Ouest (ACO) set about making extensive track improvements and infrastructure changes—the pit straight was redesigned and widened to remove the kink just before the start-finish line, and to give room for a deceleration lane. The pits complex was pulled down and rebuilt, giving more room to the teams, but thereby limiting spaces to only 52 starters rather than the previous 60. The grandstand was demolished and rebuilt with new spectator terraces and a wide ditch between them and the racetrack. Track safety technology and practices evolved slowly until Formula 1 driver Jackie Stewart organized a campaign to advocate for better safety measures ten years later. Stewart's campaign gained momentum after the deaths of Lorenzo Bandini and Jim Clark.
