The bridge uses two arms to swing a 15×15m section of road in and out of place. [2] The lift arms are oriented diagonally to the road. The bridge is painted in yellow and blue, representative of Leeuwarden's flag and seal. [ 1 ]
A swing bridge (or swing span bridge) is a movable bridge that can be rotated horizontally around a vertical axis. It has as its primary structural support a vertical locating pin and support ring, usually at or near to its center of gravity, about which the swing span (turning span) can then pivot horizontally as shown in the animated illustration to the right.
The world's longest suspension bridges are listed according to the length of their main span (i.e., the length of suspended roadway between the bridge's towers). The length of the main span is the most common method of comparing the sizes of suspension bridges, often correlating with the height of the towers and the engineering complexity involved in designing and constructing the bridge.

The bridge carries the A63 road through the south of the city connecting the west and east regions of Hull. Designed by the firm of Freeman Fox and Partners, with engineering undertaken by Cleveland Bridge, it was the largest swing bridge in Britain when it was opened in 1980. The bridge was expected to carry 30,000 vehicles a week, but by 2004 ...
A movable scaffolding system (MSS) is a special-purpose self-launching form used in bridge construction, specifically prestressed concrete bridges with segments or spans that are cast in place. The movable scaffolding system is used to support a form while the concrete is cured; once the segment is complete, the scaffold and forms are moved to ...
The swing span has a Humpback truss, while the two adjoining spans are flat-top fixed through trusses. A section of the bridge swings on a pivot point, opening up two 150-foot- wide lanes for river traffic to pass through, similar to a gate. The bridge is operated from a tower and originally ran on steam power.
The bridge rotates slowly laterally, allowing pedestrians to remain on the bridge while it is rotating. [1] The design includes a barrier on the western side to prevent entry, while, on the eastern side, pedestrians can step on and off the bridge while it is in motion. The speed of the bridge opening and closing is 0.15 m (0.16 yd) per second. [3]
A road sign indicating a bascule bridge ahead. There are three types of bascule bridge [1] and the counterweights to the span may be located above or below the bridge deck. The fixed-trunnion (sometimes a "Chicago" bascule) rotates around a large axle that raises the span(s).
