I dont think that it is appropriate to superpose a landuse over a waterway.


this is a good point, but you could spare the waterway out and just tag the construction site on the land. Depending on the details, bridge span and kind of construction, this can lead to good (temporary) representations or also be inadequate.


Devils advocate hat on:

Water is simply a land cover. So landuse is fine over water. In fact it is used for landuse=aquaculture.




Since the tag man_made=bridge is used, it seems better to  refer to the construction project with the tags as proposed by Jack Armstrong

- man_made=construction
- construction=bridge
- layer=1


there are only 40 man_made=construction in the whole world: https://taginfo.openstreetmap.org/tags/man_made=construction

the tag sounds reasonable, but it isn’t really done this way.


Yet according to the wiki a bridge is normally tagged man_made=bridge,  so it is logical to deduct that a bridge under construction should be

man_made=construction

construction=bridge

layer=1

-------------------------- Use?
Less than 10% of landuse=construction have construction=*

There are one 3 landuse=bridge.

There are over 86,000 man_made=bridge.
