Bridge design

The designed bridge is a variable depth steel beam with two spans and a single central pier in the South Dock. Each span is approximately 35m long, bringing the total length of the crossing to approximately 77m including the north abutment. It provides a permanent 15m wide and 3m high navigable channel for smaller boats to pass underneath. The north span is movable, using a bascule mechanism, to provide a 25m wide channel without height restriction for taller ships.

The deck varies in width from 7.8m on the South Quay to 15.4m on the North Quay. A triangular void in the movable span directs people away from the emergency staircase located in the axis of the crossing at the north end.

A concrete enclosure at the north end of the bridge, below the walking surface, hosts the mechanisms needed for the bridge to open and a counterweight. This counterweight helps to reduce the forces and energy needed for the operation, making the project more sustainable.

The bridge will not only improve connectivity in the area but will become an attractive element to visit. It will be accessible to every user thanks to the wide walking area and smooth slopes.
