For this project, Mr. Huijben of our sister company h3mhuijben Consultancy is the official assessor for tunnel safety. The project includes a twin-bore tunnel with three lanes in each tube. At about 2 / 3rd of the length, there is a complete underground transport hub with on-ramps and off-ramps available. This connects to a number of districts. On top of this tunnel, just below ground level, is a bus lane, also mostly in a tunnel. Along the way there are a number of bus stations.
