The A11 is the largest DBFM-project (Design, Build, Finance, Maintain) in Belgium. Jan De Nul Group provided not only design and build, but also funded the project and will be responsible for 30 years maintenance. Therefore, sustainability was paramount.
Innovative techniques reduce maintenance costs and the environmental impact. Bridges, slip roads, cloverleaf interchanges and tunnels form a beautiful, ingenious architectural warren of civil engineering structures that fit perfectly in the beautiful polder landscape. Better still, they reinforce each other. Travelling on the A11 is a true experience.
