It's not a mass edit. reach edit was individually made my me after viewing Bing imagery, looking at the error I was trying to fix, and then fixing it.

The sort of problems fixed are:

mainly highways which do not connect to other highways, for a number of reasons , including:
a) the 1st highway has been connected to a landarea which shares the same position as the 2nd highway.

b) the 1st highway has been connected to a landarea which is very close to the position of the 2nd highway.

c) the 2 highways to be joined have nodes which are in the same position, but are not the same node, so routing is impossible

d) rather than joining highway 1 to highway 2, the end of highway 1 is very close to, but not connected to highway 2.

These problems are identifiable on the routing layer of OSM Inspector. Where I have been unsure of whether something shown on the layer is a error or not I have left it untouched.
