|The mechanism by which a movable bridge moves to clear the way below.|
|Utilisé pour ces éléments|
|Outils pour cet attribut|
Use bridge:movable=* to describe how a particular movable bridge (indicated by bridge=movable) moves to clear the way below. Note that this key may be used without tagging bridge=movable, to indicate a formerly movable bridge that has been fixed shut.
Almost all movable bridges have one, or perhaps two, movable spans which are flanked by fixed spans. The way for the bridge should be divided at the ends of the movable span(s) and only the movable spans should be tagged with bridge=movable and bridge:movable=*. If desired, the piers on which the movable span rests (usually indicated by the nodes where the ways for the fixed and movable spans join) can be tagged with bridge:support=*. The pier on which certain movable spans pivot (swing bridges pivot horizontally, bascule and drawbridges vertically) can be tagged as bridge:support=pivot_pier and the support towers for the two ends of a lift bridge as bridge:support=lift_pier.
Movable bridges on highways typically have traffic barriers which should be tagged as well, e.g., barrier=lift_gate. access:conditional=* and maxheight:conditional=* can be used to tag the bridge's way and the waterway beneath, respectively, if a regular scheme exists for opening and closing the bridge.
