Hi @mapeing & welcome to OSM.  

At the Western end of this changeset you've created a couple of tunnels, one on the B260, however the A2 above them is already tagged with bridge=yes - the roads under a bridge don't need to be tagged as a tunnel.  

Also, the new roads that you've created as tunnels didn't need to be created? If possible amend existing features so we don't lose the history.

It's a lot easier if you keep the changesets to a smaller geographical area. I haven't looked at the rest of the changeset.
