The first double deck motorway tunnel in The Netherlands brings calm to the city of Maastricht.
The challenge
Burrowing beneath the city, the ‘Koning Willem Alexandertunnel’ can only open after all technical and traffic installation systems are installed and reliable.
Kicked off in 2011, project ‘Avenue2’ aims to build a double deck tunnel for the A2 motorway to pass under, rather than through the city of Maastricht.
The tunnel will divert 80% of traffic underground. This eases congestion and reduces associated air pollution. At the same time, the area above ground will be turned into a green zone with almost 2000 trees and ample space for pedestrians and cyclists.
