| Abstract: |
Bru over Otra is a newly constructed pedestrian bridge located in the Norwegian city of Kristiansand. The bridge has an overall length of 180m and provides a 4m clear width route for both pedestrian and cycle traffic over the Otra River. The bridge is made up of six spans (25m+5x32m+25m) with four piers located within the river and one located in a public park. The bridge is curved in plan and elevation, allowing for the change in level between both embankments. The deck structure is a multicell continuous steel box girder. The maximum deck depth of 0.9m is constant all long the bridge, although the transversal section is tapered at the edges. In the case of the substructure, the challenging conditions related to ice loads and the construction of the foundations and columns inside the river flow were crucial to establish their design. |
