[OSM-talk] Rendering a long tunnel

[Stephen Hope]

In Brisbane they are building a long tunnel, connecting the northern
and southern main roads and bypassing the city centre.  It is going to
go under two suburbs, the river, then another two suburbs on the other
side. There is no access except either end.  I'm wondering the best
way to render this.

On a low to medium zoom map, this tunnel should show - it's going to
be one of the main through routes of the city when it's finished.  But
on a high zoom map of the city centre, I'm wondering what it is going
to look like.  It is a very high density area, with lots of small
blocks, lanes, POI's etc., and you won't be able to see either end of
the tunnel.  How are the render programs going to handle a divided
trunk road in a tunnel  crossing the entire map tile?  Or maybe the
question should be how *should* they handle it?
