The load paths in this structure are somewhat easy to follow. The gravity load on the bridge as well as the rest of the loading on the deck such as cars are the easiest to follow which is further explained in the qualification as structural art section. The loads on the bridge due to the extreme tides are somewhat difficult to read, but they are clearly accounted for. The steel piles are the structural supports that resist the tidal loads. The piles are driven deep into the sea bed to reduce the movement on them. Having a small moment or force causing bending in the piles keeps the bridge upright. The steel is extremely strong against corrosion and are therefore the best material that could have been used in the piles.
