One of the most stand out features of this bridge, and gives it its name is the cable-stayed design. Not only is it very aesthetically pleasing but it removes the need for intermediate supports or piers in the river and allows for a longer deck. This means there is little to no construction in the river flowing beneath.
With the specification of GGBS in the concrete, the durability of the bridge is improved and makes the concrete more resilient to attack and degradation. This is especially important given its proximity to the river.
