DINKELWEG TUNNEL

This project was assigned by the city counsel of Hoorn. They requested a lightplan for the Dinkelweg tunnel which should also relate to it's surroundings. The tunnel goes underneath a railway and is used by cars, cyclists and pedestrians. The tunnel itself is only 60 meters long but if you add the start of the decent it covers 200 meters altogether. One typical aspect of the tunnel's surroundings is that it goes straight through two bodies of water which are held in place by the concrete walls marking the descent. I came to the idea that this dip you drive through should give a sensation of taking a dive through water hence the light should come from above as it would in water.

The plan consisted of a rhythmical build up of lines that come closer together in the middle and go further apart towards the ends of the tunnel implying the movement of a wave or of ripples. This rhythm proceeds in the ascent with the light coming from the ground instead of the ceiling but the lines are still progressively moving further away from each other. What I also wanted to take into account was the different speeds that people move through depending on their means of transport.

On the side for pedestrians and cyclists I mounted blue-green glass into the floor spotlights. The details within the glass could never be noticed by an automobile but a pedestrian and even a cyclist could pay attention to this. However the sensation of the rhythmical movement proves to be most effective in a car. The design of the lightplan was fully integrated in the design of the tunnel. This was all established in collaboration with the Arcadis architectbureau. It took one year to complete the whole project.
