thanks! We might need to check against the actual Roads Act in the statutebook once that is being published. The latest I could find was last year's: http://www.irishstatutebook.ie/2008/en/si/0279.html However, the list apparently refers to a mix of roads that are either completed, under construction or planned only. If I look e.g. at "the N9 from Dublin to Waterford", many sections are still a clay track currently. Even last year's road act has a disclaimer that "This Order applies only to high quality dual carriageways which were already built, under construction or in planning..." > It would be demonstrative of the power of crowdsourced data if we could > ensure that our data gets updated that day to reflect the changes > instantaneously. Since the roads are at a different stage, the practical side would not be a single day of switching. Many motorway sections under construction are in OSM already, tagged as 'highway=construction' and 'construction=motorway'. For dual carriageways already in use it would be simply a change form 'highway=trunk' to 'highway=motorway' (and for the link roads appropriately). > I imagine it will be a year or two before OSi re-issue the > Discovery Series (1:50,000) with the changes shown.

And while there is a 5th edition of sheet 50 of the OS series, most of the country is still stuck with the 2nd which misses lots of local development, bypasses and new R-roads. Their electronic map is a bit more up-to-date, so they are just too lazy to render new print versions. Teleatlas has still many mistakes, R559 in Dingle my favourite one. Up to last year it was even routed across the mountain! http://tools.geofabrik.de/mc/?mt0=mapnik&mt1=googlehybrid&lon=-10.4589&lat=52.14379&zoom=15 Their tagging of road classifications is also inconsistent throughout the country so that roads or the same class are rendered differently. > I'm not too familiar with the tagging process, but might it be an option to > prepare for this event by adding a tag to all of the sections of N Road > which are about to change, so that they can be easily changed on the day > itself? I think this would be more effort in preparing such an extra tag. Changing a road from N to M would cost only a minute, once the blue signs appear in the field.
