Yesterday evening it was announced in London that the Green Carpet has won the NCE Tunnelling Award 2018 in the category 'Project of the year for use of underground space'. The project also received a recommendation for Tunnel Team of the Year! More than 30 world renowned projects took part.

During the festival, there was a live appraisal of three of the four categories for which the Green Carpet was nominated. The team was given the opportunity to introduce the project during a 10-minute pitch and 10-minute question and answer session for each presentation.


The Green Carpet was nominated for four categories:

  • Tunnel project of the year (costs more than 1 billion dollars)
  • Project of the year for use of underground space
  • Tunnel team of the year
  • Project of the year for innovation in design and execution

The jury assessed the project on customer satisfaction, quality of the design, quality of the execution, safe construction method, innovative solutions, teamwork, collaboration, diversity in the team, sustainable use of materials and construction method.

International nominated projects included:

Metro line in Warsaw
The metro in Warsaw is one of the most modern metro lines in the world with 17 stations which connect the north and south of Warsaw. More than 500,000 people use this metro line every day. The line is being extended with a second metro line. 

The Hong Kong-Zhuahai-Macao-bridge and tunnel
The Hong Kong-Zhuhai-Macau-bridge is a bridge-tunnel combination which connects Hong Kong with Zhuhai and Macau. Bridge and tunnel have a combined length of 42 kilometres. Construction started in December 2009, the civil engineering was inaugurated on 7 July 2017 and commissioned for the public in February 2018. On 24 October 2018, the bridge was officially opened and was then the longest sea bridge in the world. 

Green Carpet A2 Maastricht
The Green Carpet for A2 Maastricht ensures one total approach to mobility and liveability through good accessibility of city and Euregion, traffic flow on the A2 at Geusselt intersection and Europaplein junction, and new opportunities for the development of neighbouring districts now that 80% of the traffic is underground.

Only thanks to the partnership within the steering group consisting of Rijkswaterstaat (Directorate-General for Public Works and Water Management), municipality of Maastricht, Province of Limburg, municipality of Meerssen and cooperation with constructor Avenue2 (the consortium of Strukton and Ballast Nedam) was it possible to achieve the innovative planning and implementation of the infrastructure for this complex project within the ten year planning and within the government budget. 

Improved accessibility, safety and quality of life
The commissioning of the tunnel at the end of 2016 was a historic moment for the city and region. The around 2 km long double-decker tunnel has 2 x two tubes on top of each other and is part of a totally renewed traffic system covering 6 km. The new traffic system means a significant improvement in the city's accessibility, traffic safety and quality of life. The through traffic flow on the A2, one of the most important motorways in our country, has also been considerably improved as a result of the tunnel. Now in 2018, the design of the new public area on top of the tunnel has also been completed, with pedestrians and cyclists being given plenty of space. This year, construction will start on the first 120 energy-neutral houses. Until 2026, another 980 houses will follow. East and west will now be united and peace and space created in the city of Maastricht.
