The invention relates to a bridge, particularly for crossing a passage of a navigation channel. The bridge comprises a section in the form of a single span (3), which may be displaced by vertical translation between a base position spanning the passage (2), in which the span (3) 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 thereof and means for lifting the span. The bridge is characterised in having only one support structure (12), provided with lifting means (14), arranged to one side (5) of the passage (2) to be spanned. The invention is of use for bridges spanning a river. |
