The St. Gotthard Tunnel in Switzerland runs from Göschenen in the Canton of Uri at its northern portal, to Airolo in Ticino to the south, and is just under 16.4 kilometres (10.5 miles) in length below the St. Gotthard Pass. It is the third-longest road tunnel in the world after Norway's Lærdal Tunnel (24.5 km), and China's Zhongnanshan Tunnel (18 km).
