Abstract
A temporary bridge includes two spans, each including at least three bridge elements to be stacked when the bridge is in a first so-called non-deployed position. The bridge elements are pivotably connected to one another, wherein two consecutive bridge elements are connected to one another by at least two linking arms mounted on the same side edge of the bridge elements. Two consecutive linking arms form a regular parallelogram with the two consecutive bridge elements connected by the arms, which can be deformed such that the movement of one bridge element relative to a bridge element immediately below in the stack of a span in the non-deployed position of the bridge causes the circular translation of the bridge element relative to the bridge element of the span immediately below. For at least one of the spans, at least one of the linking arms is shared by three consecutive bridge elements.
