 In 1970, Pas de la Casa had far fewer buildings than it does now, so the damage was relatively limited.In later years as development of the ski resort continued, plans for avalanche control measures were studied, but it was not until 1985 that strong protective features including of windbreaks and of snow fences were installed.The new CG-2 goes through the Envalira Tunnel, thus avoiding Pas de la Casa and the risk of avalanches.
