If there is a high volume of traffic from the Schöllenen (3rd class national road) in the direction of the N02, traffic on the cantonal road coming from Wassen is backtracked, as it is very difficult to enter the roundabout (not entitled to give way, large longitudinal gradient).

To solve the problem, the existing Göschenen roundabout is to be replaced by a new bridge (Wassen - Göschenen) and a T-junction (Andermatt, Göschenen, N02), according to variant 2 of the four variants considered so far. The subject of this call for proposals is engineering services in the fields of routes, engineering structures, geotechnics and natural hazards.

It is the best option for the choice of lines, including a suitable, slender, architecturally appealing bridge construction. Furthermore, the need for repair of the pre-tunnel (coordination with project 1TG) and the clean unbundling of non-motorized traffic from private transport must be taken into account.
