text: I don't believe that all the extra roads mapped here actually exist.  The corresponding roundabout the other side of the A1 had a similar problem, which I fixed in http://www.openstreetmap.org/changeset/36488962 , but didn't get enough time to look at the layout this side of the A1.  Although http://www.openstreetmap.org/way/27248869 does exist as mapped, I suspect that http://www.openstreetmap.org/way/177662105, http://www.openstreetmap.org/way/307620649 and http://www.openstreetmap.org/way/231963920 do not.  Needs a proper check though
