Pontoon bridge is fitted with hydraulic rams between the pontoon and the brdge deck and a reference system (clump weight/wire) running from the pontoon to the river bed. Pontoons are fitted with tidal turbines. Power from the turbines is used to move the rams up and down, conmpensating for the movement
of the pontoons, keeping the road level. Surplus power is sent to the national grid. Elegant. Excellent.
