Abstract
A bridge for crossing a passage of a navigation channel includes a section in the form of a single span, which may be displaced by vertical translation between a base position spanning the passage, in which the span rests on fixed support sections of the bridge, and a raised position, for opening the passage, and a support structure for the span on displacement of the span, and a drive for lifting the span. The bridge has only one support structure, with the drive, located on one side of the passage to be spanned.
