[solved] Messed up roundabout rendering

General talk

Hi, I’ve got a bit of a question about why this rendering works like it does:

http://www.openstreetmap.org/#map=17/50.63446/-2.46397

Note the different rendering of each roundabout. The left and right roundabouts look fine, with the joining roads connecting neatly, but the middle roundabout has the white unclassified roads rendered over the top, which looks confusing.

I thought it was just unclassified roads being awkward, but this other roundabout renders OK. Blows that theory…

I think this is because the roundabout is tagged as highway=trunk_link
It seems there are some bugs with rendering of link roads. ie sometimes they don’t appear to join properly to other roads. There have been a few bug reports, but I don’t if any of this has been fixed.

I think this is an mapping error anyway - the roundabout should just be tagged as highway=trunk. Because it is part of the trunk road. ie if you are driving along the A354, you have to go around the roundabout.

Ah, changing links back to ordinary roads fixed it. Which makes sense, I guess, as the main road should be rendered over the top of a little link/slip road. Thanks!
