The A2 motorway, so-called Gotthard route, is one of the most important North-South transport arteries in Europe and one of Switzerland’s busiest motorways.
Thousands of car and lorry drivers use the route on a daily basis, which runs from Basle via Lucerne, then through the Gotthard tunnel to Lugano and continues on the Italian side in the direction of Milan. This heavily traffic stressed route passes through the San Salvatore Tunnel in Ticino.
