I had started deleting unnamed AND ways to make the task easier, but that
didnt help too much as you lose the reference street geometry to match with
the yahoo imagery.
I feel the best way to fix the map is to remove all the AND paths
completely, start tracing the roads and name them by using an old extract of
the original AND import as reference. Good idea?
