Abstract
The Yumemai Bridge is a floating swing arch bridge constructed across a water channel and supported by two hollow steel pontoons in the Port of Osaka. It connects two reclaimed islands to the regional road network and can swing around a pivot axis near one end of the girder with the assistance of a tug boat. The design of the bridge specifically addressed the action of waves, wind and earthquakes, the required swinging mechanism and the issue of durability. The pontoons are made corrosion-free with their side lined with titanium plates and with the other wet surface by cathodic protection. The mooring system consists of dolphins with movable reaction walls and rubber fenders. The reaction walls are located on the fixed dolphins with piles driven in the seabed. The structure is designed to be strong and stable enough to withstand typhoon-level winds and waves.
