Road Conditions
The St. Gotthard tunnel forms part of the A2 motorway in Switzerland, running south from Basel through the tunnel down to Chiasso on the border with Italy. Traffic flows through only one tunnel, which carries traffic both ways, with each direction allocated only one lane. The tunnel's speed limit is 80 km/h (50 mph).
Heavily used, the tunnel often has traffic jams, on both the north and south ends. In contrast, another tunnel through the Alps, the San Bernardino road tunnel in the canton of Graubünden farther east, is relatively uncongested and shorter, but the road taken on that expressway is longer than the direct route through the St. Gotthard tunnel.
In the tunnel, a distance of 150 m (490 ft) between each truck is enforced.

“The right road lies under your tongue—just ask.”

“Mankind always sets itself only such tasks as it can solve; since, looking at the matter more closely, we will always find that the task itself arises only when the material conditions necessary for its solution already exist or are at least in the process of formation.”
