<pre wrap="">Hi all,
up to now I've used tunnel=culvert
<a class="moz-txt-link-freetext" href="http://wiki.openstreetmap.org/wiki/Tag:tunnel=culvert">http://wiki.openstreetmap.org/wiki/Tag:tunnel=culvert</a>
like this:
1) JOSM warns that a waterway and highway are crossing
2) I split the waterway into 3 parts and add
tunnel=yes, layer=-1 to the short one in the middle (or
split the road and add bridge=yes,layer=1)
</pre>

I keep the stream at layer=-2, I add the culvert in an additional
small way segment on top at layer -1 and both are crossing the road
which is at layer=0.<br>
This keeps the stream at layer=-2 from spring to end, which is
perfectly correct and convenient.<br>
A Nominatim search of a JOSM selection shows the whole stream and
not stupid pieces.<br>
<br>
I never understood the remark "it is not necessary to not split, one
can consolidate splits in relations (easy, isn't it)". To me, it is
"it is not necessary to split". Why not avoid splits in the first
place?<br>
The same can be done for bridges which are in fact pieces of
concrete under the uninterrupted tarmac foil and not an interruption
(split) of the road.<br>
<br>
I once wrote an OVERLAY suggestion (to be discussed, that I much
improved since) that generalizes the principle of an overlay way
segment that, in one of its usages, applies tags such as speed limit
to a segment of the highway. Roads, as seen by an editor, Nominatim
etc., are kept unsplit but the programs that do not want to deal
with the overlay segments can prepare the OSM data by using the
overlay ways to split the main ones, discarding them and continue
with the same logic as presently.<br>
In a second usage, it can avoid a hiking route that is using a main
highway over 50m before leaving it to split that main highway.<br>
