The tag man_made=tunnel
is used to tag a tunnel, defined by the outline of the tunnel. It is suitable to group together all ways running into the tunnel and for holding descriptive tags for that tunnel (the object represents the tunnel as a whole).
Current status
Although a proposal exists, it never went past the draft stage. Nonetheless, there is a constant increase use of this tag, and has gotten official iD support in May 2019[1] but as of Sep 2024 isn't universally supported either (e.g. JOSM lacks the corresponding rendering and templates).
How to tag
(Note that this description is based on man_made=bridge
but is intentionally lacking details due to the aforementioned lack of official acceptance.)
Draw an outline of the tunnel as an area and apply
man_made=tunnel
and layer=*
to it. The outline should encompass the continuous structure of the tunnel.
Additional tags on the man_made=tunnel
outline:
name=*
– name of the tunnellayer=*
– to describe the vertical relationship with surrounding features
Ways in and on the tunnel:
- Connect the road
ways running into the tunnel to the
man_made=tunnel
outline where the ways cross the outline. Mark these ways withtunnel=*
. - Do not connect the
ways above the tunnel to the outline.
