ABSTRACT
A 4 km long sea-crossing structure will be rising out of Storstrømmen in Denmark over the coming 3 years. The new structure will be one of the few bridges, in the world, carrying a two-track high speed railway and 2 lane road, as well as a combined footway & cycle path, on one single cross section. Comprising 44 viaduct spans and 2 navigational spans. The main bridge will be a cable stay structure with a 100 m tall pylon. The Design & Build Contract was awarded in February 2018, the detailed design is now well on the way, with construction almost about to start. The paper gives details of the overall project, outline the development of the architectural concept for the cross section, and the development of the Definition Bridge Design and the Design Basis for this mega structure. A process which started in 2013 and has continued right up to the issue of the Final Tender documents in May 2017, with significant changes being implemented throughout the competitive dialogue phase with the prequalified D&B consortia’s, as a result of the dialogue. The new bridge will be an outstanding landmark, replacing what was once, and for 30 years, Europe’s longest combined road and railway bridge.
