[OSM-newbies] Dual carriageway bowties

[Owlman]

Hello -
What's the easiest way to fix bowties / pinch-points at a
dual-carriageway intersection?--that is, where the two parallel ways
merge to one node where they intersect the cross-street.
I think I remember reading about this on the Wiki (it was a problem
from the TIGER import perhaps?) but now I can't for the life of me
find that page :)

thanks,
-Noah
