It routes correctly now, routing etc usually takes a little while to update

Hi Puxim, I've reverted your edits changing the road catagories and numbers through Wantage town centre.

Road signage says that the A338 no goes through the shopping area itself, by the looks of it this was changed about 10 years ago.

Google Maps still classes the roads as you've put them but this is outdated; please refer to ground truth rather than other maps.
