Limitation of the driving speed in the Arve Valley

From today and until 31.03.2018, the driving speed in the Arve Valley will be reduced. On the highway during the winter months, only 110 km/h instead of 130 km/h are allowed, also the speed on the secondary roads is reduced to 90 km/h instead of 110 km/h. The Arve Valley knows a strong air pollution and has therefore introduced a ZPA.
