18.059.02 | Bridge ‘Centrumbrug’

The adaptation of the river profile between Lys and Menin is an opportunity for a fundamental and large-scale transformation of the city centre. Promenades along the Lys, new public spaces and the bridges (traffic and bicycle bridge) have been designed to create a coherent ensemble. From the engineer’s point of view, it is a hyperstatic frame-bridge with a central supporting structure, whose lateral spans have been designed to prevent any tension on the support devices. The form in plan-view generates an overall torsion that is balanced by a meticulous choice of the position on plan of the support points provided by the intermediate piles. To facilitate assembly, the main structure is made entirely of steel. The deck is made of in-situ reinforced concrete, the formwork being supported by the metal structure.
