It's not Lange Wapper any more :-)

I put them in when it was decided that it'll be built at that location (and I 
really don't see our governments opening up this discussion again...). The 
roads only got in OSM after the decision was made to make tunnels there. The 
A102 for example doesn't have a highway=proposed (although the track is in 
OSM) since it's not really decided yet how to build it (and it'll be post-2020 
anyway once they start that).

In the Cadixwijk in Antwerp there are also some streets that aren't built yet, 
but which already have official names. You can only map these as proposed.

They don't harm the map, and they give an idea about changes that may have to 
be done in future on the map.

Especially for big roads I'd like them in OSM, like N19g (Kasterlee-Geel), 
N171 (E19-A12) (in OSM) or N74 (Hechtel-E314), A11 (between N31 and N49 near 
Brugge) (not yet in OSM)

Anyway, it's useful geographical data. If you're don't want to see them, just 
don't render them :-)

I'm still wondering how to map those bridges in Varsenare :-)
