Ireland North
 Here is OSI's regional map of Northern Ireland. This particular section shows Belfast, Northern Ireland's largest city.  Scoll down and you can see Belfast. These maps are excellent for trip planning. As you can see the red route numbers for the Ireland road system are well marked on the map. But... it's easy to lose track of those numbers when you get in a  large city. Get a city map to get through large cities on your route.  See a Belfast Map
