| Abstract: |
The crossing of Sulafjord on the Ferry-free E39 project in Norway with a bridge solution is an extremely challenging task. The fjord is 3 to 4 km wide, 450m deep and located in a harsh weather environment with strong and heavy winds and waves. The AMC group (consulting companies Aas- Jakobsen, Multiconsult and COWi with subconsultants) has recently developed four different suspension bridge solutions for this crossing in an extensive preliminary design phase. Client for the project has been the Norwegian Public Roads Department (NPRA). These four alternatives involve a world record singe main span of app. 2700m as well as two long-span double span suspension bridge solutions on GBS (Gravity Base Structure) foundation and a triple span floating suspension bridge solution on TLP (Tension Leg Platform) foundation. |
