An inflatable lifesaving gallery bridge comprises a pair of inflatable beams(6) positioned on the left and right sides of the bridge along its length direction, a bottom plate(5) disposed between the inflatable beams, a connecting means(8) positioned on at least one end of the bridge for connecting with other waterborne vehicles, an inflatable cover(11) disposed between the inflatable beams to cover the bottom plate, therefore forming a holding space, an air charging system(10) to charge the bridge, a drainage system(12) to expel water from the holding space. The bottom plate can be bent transversely on at least one position of the plate in its length direction. The gallery bridge can be used to save people after being inflated immediately, and can be folded when the bridge is not inflated, thus occupying a smaller space.
