Hello, Welcome to OpenStreetMap.

I've looked at your mapping and unfortunately, there are serious problems. 

There are several duplicated highways, one road placed on top of another. This seriously disrupts routing. Also, a lot of your mapped roads are tagged as oneway which seems to be illogical and again disrupts routing. Then there are several route relations that do not look correct and in any case, are incorrectly tagged. These comments likely apply to all of your mapping.

Could you please go over all your mapping and make corrections? Although I think it might be easier to revert it all and start again, perhaps after gaining a better understanding of OSM best practices.

Need any help please just ask. Regards Bernard.
