Discussion: The Architectural Expression of Moving Bridges
In a world in which physical systems of communication such as roads, railways, canals, rivers, etc. are used ever more intensively, bridges are vital in allowing one mode of transport to cross another. In that respect, they obviously create links. Less apparent, however, is the fact that they can also create obstacles, in which case they need to be designed in a movable form. Which of the various transport systems may be interrupted will depend on the flexibility of the routing and the loss of time that is acceptable in such a situation. That is why shipping usually has priority at points of intersection, while pedestrian, road and rail traffic can be briefly interrupted at a movable bridge.
