Objecti tive ves that at apply t y to the p process ss of d design gning t g the brid ridge:
- Lowering risk and increase the robustness to obtain a high
degree of safety in all aspects
- Develop a solution which emphasis good architecture for the
surroundings, for travelers and the road as an attraction.
- Lowering costs of construction, maintenance and operation
- Low impact on environment
- Low impact on marine traffic
