Devils advocate hat on:

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

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.
