EP border LU/NW - Hergiswil

The busy section of freeway between Lucerne and Stans is an important piece in the puzzle of the Swiss north-south axis. In addition to the widening of the freeway, repair work is also being carried out on the existing infrastructure.

On the A2 freeway from Lucerne in the direction of Brünig or Gotthard, one currently drives through the two and a half kilometer long construction site in Hergiswil. The construction site begins approx. 150 m after the Spier tunnel up to and including access ramps N08, from and to Sarnen.

Project objectives

The client is pursuing three project goals with the initiated measures:

In view of higher traffic volumes, the emergency lane will be widened by approx. 1.50 m on the lake side. This makes it possible to convert the emergency lane into a temporary third lane during traffic peaks in the northbound direction.
The fire protection no longer meets current requirements and must be renovated. The goal is to achieve an improvement in noise protection. This in view of the fact that the nearest properties are located immediately behind the highway.
In addition, the building is not considered earthquake-proof. This is to be achieved by bracing the gallery.

Special features

The greatest challenges in the project are the complex construction sequences with strongly changing personnel, coordinated with the demands of the respective construction phases, as well as the limited space for personnel and installations.
