The Gotthard Road Tunnel in Switzerland runs from Göschenen in the canton of Uri at its northern portal, to Airolo in Ticino to the south, and is 16.9 kilometres (10.5 mi) in length below the St Gotthard Pass, a major pass of the Alps.

[2] Although it is a motorway tunnel, part of the A2 from Basel to Chiasso, it consists of only one bidirectional tube with two lanes.

[4] The tunnel rises from the northern portal at Göschenen (1,080 m (3,540 ft)) and the culminating point is reached after approximately 8 kilometres (5.0 mi).

In response to the automobile boom in Switzerland and other things, the Swiss government gave approval in July 1969 for the construction of the 17-kilometre (11 mi) Gotthard Road tunnel.

Following the catastrophic fire in the road tunnel in 2001, car shuttle trains resumed operations for a few weeks.

It has four large ventilation shafts and an additional side gallery between 10 and 18 metres (33 and 59 ft) from the main tunnel, having its own independent ventilation system in order to facilitate the cutting of a second tunnel, should future traffic levels require it.

[8] In March 2014, the Swiss Government approved a bill to allow the building of a second road tunnel.

[13] Work on an access tunnel started in September 2021,[14] and a major contract for the project was awarded in August 2022.

[15] A joint venture between Frutiger, Implenia and Webuild & CSC SA were hired to construct the new tube and a parallel access tunnel.

Heavily used, the tunnel often has traffic jams during peak holiday seasons over Easter and summer, on both the north and south ends.
