Requires
Useful combination
Status: In use

Used for simple-suspension bridges in combination with bridge=yes. This may be used for extremely simple 3 rope bridges, "Tibetan" or "Inca" type hanging bridges or more modern hanging bridge constructions such as the Wikipedia-16px.png Passerelle himalayenne du Drac.

Compared to bridge:structure=suspension the body of the bridge is not a rigid block but can swing, although modern constructions typically use additional cables to minimise swinging.

How to map

  • bridge=yes + bridge:structure=simple-suspension
  • highway=footway/path
  • layer=1
  • cable_number=* - number of main cables/ropes if known.
    • 1 - zip-line, see below
    • 2-3 are most primitive bridges, walking on a single rope with one or two ropes as railings
    • 4 rope bridges usually have some kind of plank deck, 6 rope bridges are more advanced
    • 8 or more cable bridges are usually more or less stabilized to minimize swinging
  • width=* (usually less than 1 meter).

Highway/trail type should reflect the expected use, most simple-suspension bridges will be usable only for hikers (highway=path or highway=footway).

Fine-grained access=* -type restrictions like bicycle=* (no or dismount), horse=* can be used. For mountain bikes use mtb:scale=* and mtb:description=*

Bridges requiring special skills may be additionally tagged with sac_scale=*, those requiring special equipment with highway=via_ferrata.

Bridge name often may provide details on structure.

More fine-grained characterization of bridge construction is being considered, so far a freeform text description can be given with description=*.
