[OSM-newbies] Underway road.

[Xan]

Hi,

I have a situation where a road is underway in a building. How can I 
mark that?
This is the situation: 
[http://www.openstreetmap.org/?lat=39.585385&lon=2.631358&zoom=18&layers=B000FTF]
You could see the google maps 
[http://maps.google.com/maps?f=q&source=s_q&hl=en&geocode=&q=son+dameto,+palma,+mallorca&sll=37.0625,-95.677068&sspn=33.901528,79.013672&ie=UTF8&hq=son+dameto,&hnear=Palma,+Spain&ll=39.585477,2.630716&spn=0.000503,0.001206&t=h&z=20]

that the road is underway a road and then a building (I'm refering to 
the 180 angle). I suppose it has, at the end, a parking.

Thanks,
Xan.
