Bridge Kop van Kessel-Lo - 06.040
Program
Complete structural engineering and architectural design for a bridge as well as the retaining walls of the square underneath.
Concept
Given the complex urban context, a holistic design approach was chosen: The retaining walls, the associated functions, the bicycle tunnel and the bridge itself have been designed as a sculpture. The whole structure appears as a single gesture allowing smooth traffic flows. The slopes of the ramps connecting the bridge to the public square underneath are limited to 4% to maximise user comfort, while staircases enable more direct connections. The square integrates naturally into the pedestrian flows from the railway station. The finishes chosen for the different elements help identify their purpose. The sandstone texture used for the bridge and the walls is a direct reference to the city of Leuven's built patrimony.
Specific features
The bridge, the tunnel and the walls under the bridge are one monolithic element and founded on just a pair of 6 compaction-bored piles. The typology of the bridge is that of a moment frame. The horizontal reaction at the abutment is resisted by a reinforced concrete tie passing underneath the public square.
