Project: A4-tunnel Delft-Schiedam

The new A4 Delft-Schiedam highway, a seven kilometre long road ensuring less congestion on the A13, opened in December 2015. The Kethel tunnel, a 2 kilometre long land tunnel that runs through residential areas, is one component of the highway. The ICT Group was called in to ensure the safe control of all technical tunnel equipment.
