In 1994, 52 per cent of voters back the Alps Initiative. It calls for the Federal Constitution to protect the Alpine region from the negative impact of traffic and forbid the expansion of through roads. Additionally, traffic is to be shifted from road to rail. The decision accelerates the development of the NRLA and shapes the 1999 transport agreement with the European Community.
