Erasmusgracht, a key element in Nieuw-West, runs straight through an area with on one side the neighbourhood Kolenkitbuurt and on the other side the area Laan van Spartaan, which is currently under development. For pedestrians and cyclists, these two districts are already connected by bridges along the A10 orbital motorway and near Leeuwendalersweg. A new bridge has now been built in between, which when the new development has been completed will be part of a main route to and from Bos en Lommerplein.

The bridge catches the eye here because of its sculptural character. From a single asymmetrically positioned support in the water, the ends rest on the green banks of the canal. The bridge does not have heavy abutments, but rather light ends which can absorb the contraction and expansion of the bridge under the influence of temperature fluctuations.

The structure consists of two steel main girders on either side of the bridge deck. These girders follow the so-called ‘momentum line’ and together with taut steel cables also form the low bridge rails. The steel plates have a light grey coating and are folded sharply like paper, giving rise to constantly changing perspectives when the bridge is approached. Sunlight on the surfaces and its reflection via the water reinforce this effect.

The bridge’s total span is 50 metres. The height above the water is high enough for small boats and skaters and allows small animals to follow their own, ecological, main route on the canal banks. (ARCAM/MB/MK)
