The Tremola San Gottardo, located in the Canton of Ticino, is the longest road monument in Switzerland and is listed in the inventory of the historic Swiss roads (IVS).[1][2] It connects the municipality of Airolo (1175 m a.s.l.) to the Gotthard Pass (2106 m a.s.l.).
One of the highest paved roads in Europe, located on the left side of the Val Tremola, it was constructed with the opening of the roadway of the Gotthard Pass. In its most important stretch, over a length of four kilometers it climbs a height of 300 meters in 24 hairpin bends.[3]
