Eilandbrug Kampen

The Eilandbrug is an asymmetric cable-stayed bridge made of steel and concrete across the IJssel in the N50 motorway near Kampen. The bridge has a fixed and a movable component (bascule bridge).
The total length of the bridge is approx. 412 metres, with a free span of approx. 150 metres.

Hollandia was the main contractor of this project. The civil-engineering work was carried out on a subcontracting basis by the Hegeman beton- en waterbouw and Strukton betonbouw consortium.

The total length of the bridge (412 m) was determined by the width of the winter bed of the IJssel. Its altitude is extra high, as the number of sailing boats to pass underneath the bridge freely has to be as high as possible.
The navigable section of the river (the summer bed) requires unrestricted headroom with a width of 20 m, needed for high sailing boats of the so-called ‘Bruine Vloot’.
This waterway is spanned by a hydraulically driven remote-controlled bascule bridge made of steel. This moveable bridge, which is connected directly to the main span, is made entirely of steel and has an orthotropic deck. The bridge and fittings were made entirely at Hollandia’s workshops.
The special aspect of this remote-controlled hydraulically driven bascule bridge is its counter weight.
This ballast block is not hidden away in a bascule basement, but has been installed in plain view.
