Gotthard Tunnel
The Gotthard Road Tunnel is one of the three tunnels that connect the Swiss Plateau to southern Switzerland and run under the Gotthard Massif, the two other being railway tunnels, the Gotthard Tunnel (1882) and the Gotthard Base Tunnel (2016). All three tunnels bypass the Gotthard Pass, an important trade route since the 13th century. The pass road culminates about above the tunnel, at a height of , and is only passable in summer.
