Hi, Welcome to OpenStreetMap.

Unfortunately, you made quite a few mistakes here, as indicated by the warnings given above. The unjoined crossing highways and many duplicated sections of highways are particularly problematic as they would disrupt routing. 

I think I've fixed all the highway problems, but several more minor problems likely remain.

Please take care when mapping or correcting highways. Please don't duplicate any highways or sections of highways. Please don't cross a highway over another without joining them. 

Regards Bernard.
