ABOUT THE PROJECT

These 2.3 km long double-layer tunnels with their exceptional design is a first of kind in Europe, suitable for passenger cars, lorries and trucks. The tunnel separates local traffic from transit traffic and advances a green environment for the citizens, as part of an integrated and sustainable plan for the city and the motorway. The plan entails multiple objectives for the improvement of the traffic flow on the A2 and the accessibility of Maastricht, as well as one that promotes the quality of life and road safety, resolving bottlenecks within the city, and creating opportunities for urban development. The integral area ‘The Green Carpet’ is designed on top of the new A2 motorway tunnel. A long, intimate tree-lined ave nue above the tunnel is the connecting element between the adjacent city-districts. Moreover, the project contains more than 1,000 dwellings and 30,000 square meters of commercial real estate, all filled with more than 1,000 trees winding through the city.

THE HIGHEST SAFETY

Novenco Building & Industry (NBI) was awarded the contract for both the tunnel ventilation system and the pressurization system of the escape routes, including system engineering, delivery, mounting, commissioning, factory acceptance tests (FAT), site acceptance tests (SAT) and handover. For the four tunnel tubes, NBI delivered in total 66 fans for the ventilation, escape routes pressurization systems and smoke control system in case of a fire in the tunnel. All axial flow fans and tunnel jet fans are executed in highgrade (AISI 3.16) stainless steel. All fans are certified as a smoke extract fan in the class F300 in accordance with the European Standard EN 12101 (tested 300°C for at least 2 hours).
