. The bridge would have a single main cable and a split bridge beam. The cable would run down the centre of the bridge, with the lanes on each side of an open area with cross-sections. While this method is more expensive, it allows for a more aerodynamic bridge. The bridge would have two pylons, with the road lanes crossing on the outside of the pylons. Each pylon would be tall. The pylons would be round with a diameter of between . The northern pylon would be anchored in bedrock, while the southern pylon would be anchored in a caisson in bedrock, located below

mean sea level There are several kinds of mean in mathematics, especially in statistics. Each mean serves to summarize a given group of data, often to better understand the overall value ( magnitude and sign) of a given data set. For a data set, the '' ...

. The distance between the middle of the lanes would be at the pylons, and at the middle of the bridge. The main cable would be above the sea at the pylons and above the sea at the middle. The bridge allows a clearance below of , wide. The crossing would establish a
