Comparison of a Single and Double Main Span Suspension Bridge for the Western Scheldt Crossing

The option of a double main span suspension bridge has thoroughly been studied in the Netherlands as an alternative to a bridge with a very long single main span. This paper presents the conclusions of that study, along with comparative conceptual designs of both bridge options. The study and the designs allowed pronouncing the double main span bridge feasible despite the large horizontal loads on its middle pylon. The results can be indicative for prospective multi-span suspension bridges.
