Why did you delete the give way node?

I was just on that section of road today and there is no actual speed limit signs. Approaching the roundabout from Enniskillen side the only sign is a warning roundabout ahead. Even when you get on the dual carriage way there are no signs saying 70. Coming back the other way from dual carriage way to Enniskillen there are warning signs saying Reduce Speed now, but the rumble strips force you down to about 30-40mph. Heading for Enniskillen, there was merger signs for the two lanes coming off the roundabout into one lane, but no speed signs. Feel like tweeting PSNI for comment?

When I was learning to drive, any area that was lit by overhead lights, was assumed to be 40mph unless otherwise stated ie 20mph around schools or 30mph in built up areas

Pretty sure a lot of these areas are lit, therefore speed limits are reduced to 40mph. There are also rumble ramps coming off the dual carriageway onto the roundabout, but no physical speed limit signs (way:262097519). These sections were purposely not tagged because the actual speed limit is not stated.

Is this the roads actual name? If not, name should just remain blank

I was under the impression that we used this tag to indicate a dead end (you would need another mode of transport to continue ie a ferry) and was to help routing. Part of the road is public, therefore has an official road name, maintained by the Roads Service or whatever they call themselves these days.

Pretty sure this was discussed with OSMIE members at the time and what I have always used to indicate a particular road is a "dead end".

Last time I was in the area it was definitely a locked cabinet they were operating from.
