Staying on the bridge
The basic structure is a special version of an arched bridge, which the designers also call a ‘body bridge’, because the forces needed to carry the enormous deck are contained in the bowed shape of the four legs and back of the bridge body. Their effect is like that of the hull of a ship.
Anyone not wanting to get quickly to the other side, who instead has the bridge as their destination, is carried by the escalators in the four arched legs into an enclosed garden on top of the back of the giant animal that has stretched out across the Creek.
