The Bering Strait of today is characterized by a harsh environment and enormous natural forces such as pack ice flow in the sea channel. Any typical bridging structure would have to withstand these forces and cause massive constructional efforts. The design of a crawling float bridge is interacting with these forces. By swimming on water and crawling over ice, the bridge is able to minimize the contact surface or rather all pushing forces. Linked by hydraulic systems the flexible pontoons and the stiff vehicle traffic deck can compensate the interactions between each other. Like modern wave power plants it also uses the constant movements to generate energy. Connected with a strong pulling cable in the center of each bridge deck module the float bridge is linked to 12 anchor modules to keep the bridge elements in position like a counter bearing. (...)
