This floating pedestrian bridge  can sail along rivers and oceans like a boat. Designer Margot Krasojevic conceived the bridge as a flexible structure that can be folded, stacked and expanded so that it can be moored along quaysides, sailed to different locations, or permanently positioned. The Ordos government commissioned Krasojevic to design a pedestrian bridge which would cross the Wulanmulun River, located in Ordos city, Kangbashi district Mongolia. The SailBoat bridge consists of a main floating section, three expanding walkways, and a carbon fiber triple sail. The sail can be lowered and raised by a buoyancy rotator and allows the bridge to function as a sailboat in order to reach new locations. Cylindrical cross-flow turbines function as rafts and help stabilize the primary structure.

The walkways are flexible and can adapt to different spans. Caisson foundations and screw-in moorings can be used to permanently stabilize the bridge. A rotating Mobius ballast chamber hydraulically operated by a thruster and powered by photovoltaic cells rotates the sails which are made from lightweight aluminium and carbon fiber-reinforced polymer. + Margot Krasojevic Architecture
