Cork County Council in conjunction with TII (Ireland’s authority for major roads) are in the process of building a bypass past Macroom and Ballyvourney in Co. Cork, Ireland.

Recently, I was travelling back from Killarney and noted that the road had been re-aligned. I quickly captured some GPD traces and have now updated OpenStreetMap with the new roundabout and re-aligned N22 (the bypass will assume the N22 name I presume when it opens).

This was a relatively nice edit to undertake. While I only had one trace to work with, it was good enough to get a rough idea of what needed to change. I also had to amend the N22 route relation(s) - there were two; one in each direction. I didn’t have a whole lot of experience editing these types of relations but the josm interface was intuitive.

As always, I wanted to validate my work (especially as I was editing a primary national route in Ireland). ra.osmsurround.org is a great tool for that so I checked both relations for issues (see relations 3147725 and 558006).

I expect more changes in the coming months as work progresses on this road.

Finally, I checked to see if other map providers had picked up on the change. Funnily enough it appears that Google have picked up on it (possibly using data from Google Maps’ users) but in much lower detail. I guess their algorithms detect something is up but don’t know how to deal with it properly yet. 1-0 to OpenStreetMap!

p.s. Driving round the roundabout 3-4 times was quite fun and a great way to get a good trace for it.
