Since at least 350,000 visitors were expected again and the old naval dockyard is surrounded by water, additional access roads had to be created for the walking public, something that can usually be solved with average pontoon bridges.
But in this case the bridge had to have a navigable section, because the ‘brown fleet’ had to pass through and also for emergencies. This is no problem at all with the latest certified VSP pontoons. The middle section can be opened and closed at any time by means of a hinge construction, whereby the closing side of this type of bridge consists of two specially designed bridge pontoons (colored light gray in the illustration).
The lengths of the openable part and the floating abutments are variable. This means the system can be adapted to any location. Furthermore, the bridge is equipped with barriers to temporarily stop the public when the middle section is open.
