When looking at the loading due to wind loads on the bridge the main portion that is important to analyze is the main spans. Because the two main spans are relative short the wind loading is insignificant. The wind loads however would be accounted for due to the outward bend of the towers that support the tension cables. This theory of widening the bottom of towers was first used by Gustav Eiffel when constructing the Eiffel Tower. The bent shape is very good at transferring the wind load to the base supports of the structure.
