Purmerend, Netherlands, 1995–1996
An intense mixture of technique and infrastructure has resulted in a bridge consisting of three individual decks, which open and close asynchronously, imitating the movement of playing fingers. In the flat polder landscape, the bridge links a new housing development to the main road. The longitudinal separation of the bridge deck into two pedestrian and cycle routes and one road for cars enhances traffic safety. The finger-like arrangement also results in extra mooring space for pleasure boats. A cycle path runs below the bridge, along the waterfront.
The bridge elements are controlled from the bridge master’s house, a small edifice that is perched 8m above the water level. Perforated steel plates, which are applied to the concrete core of the building, make it semi-transparent.
