This bridge will connect the two parts of the Athletes’ Village between the cities of Saint-Denis and L’Ile-Saint Denis, which is part of the structures of the Paris 2024 Olympic Games. It will be dedicated to pedestrians, cyclists and buses. It crosses the Seine without being supported within the river (free span between the C0 west abutment and the P1 support of 109 m) thanks to its design with a V-shaped slant-legged intermediate support (P1) located on the east bank. Between support P1 and abutment C2 it also crosses the RD1 road network over a length of 29 m. Its total length is 138 m with a variable width of 18 to 23 m, including two lanes for road traffic (buses) of 3.50 m each.
The structure is a composite bridge comprising four box girders of variable height connected with transverse beams. Pre-stressed cables are designed and placed in pairs inside the four box girders. They are anchored to the C2 abutment to the east.
The assembly of the structure is also of particular interest: after assembly of the steel structure at the port of Gennevilliers and transport by boat to the site of the final installation of the main section weighing 1500 t, the structure is placed on its final supports.
The delivery of the structure is planned in the summer of 2023 and the total budget is 31.2 M€.
EQUILIBRE, in collaboration with Bureau Greisch (Bélgique) and on behalf of Eiffage Métal (steel contractor), carried out all the execution studies on the steelwork of the structure and the principal temporary equipments, as well as the necessary capacity and deformation verification studies during all the assembly phases.
