can a seasoned highway mapper fix everything i've done wrong here?  this is a new USian roundabout seen on Bing z19, which i moved against z20 where the older road layout can be seen with the origin of the turn restrictions, one-ways and extra ways I've left intact.
please fix/delete/whatever to be correct, if you know the things i would have to guess at.
thanks
