An important part of the Zurich West bypass is an imposing double tunnel that will take altogether six lanes.
|
|
The tunnel consists of two parallel rectangular sections, and forms part of the 16.6 km longest Swedish motorway project.
|
|
The existing Elb tunnel, commissioned in 1975, with three separate tunnels and six lanes was no longer capable of carrying the present-day volume of traffic.

|
The construction of the A5 motorway between Neuchâtel and Yverdon includes a 481 m long tunnel near d´Areuse.

|
The construction of this double-lane, 180 m long roadway avalanche screen was carried out in two working stages.
