BRIDGE OF STICKS - PURMEREND
The "Bridge of Sticks" is a bicycle/pedestrian bridge that connects the new Vinex Weidevenne and the polder Wijdewormer South-West of Purmerend.
The client, the municipality of Purmerend, wanted a landmark bridge that still reserves and integrates within the surrounding nature. In addition to the budget for the bridge, also the arts budget of Weidevenne was made available to strengthen the ambition to create something special
There is a minimal and sustainable use of materials to give the bridge a light appearance. Between two rows of 16 columns a thin, aluminium road, hangs on 64 rods. The bridge is composed of 8 "tables" of 16 meters, which gives a total length of 128 meters. Each bridge part is carried by four columns and is an independent construction stabilized by the cables. With the stability bars at the bottom of the deck, the columns and the hanging bars the bridge is a kind of tensegrity structure which changes in appearance from different angles.
In 2002 the bridge was nominated for the National steel price. Quote from the jury report:
"This tensegrity construction is beautifully integrated into its surroundings. The composition of the slender pylons and a thin bridge deck, floating hung on tension bars, increase the perception of the surrounding nature. The bright, almost fragile construction is not obtruding but yet an iconic design. From far the bridge reveals itself as a natural finely-meshed network. Up close the minimal material usage is clear. Exciting is the chamber in the bridge deck across the full length by varying the tension in the steel lower and upper cables. A smart method. The coordination in the use of colour and detail strengthen the image of the bridge as a single construction. "
