Black line on some roadways

[skorasaurus]

I came across this while working on #105 ;

the fault is not highway=construction, I have seen other ways styled properly with just highway=construction

there's another tag here that is the culprit but haven't narrowed it down yet. My initial guess is construction=* tag.

The way in question is http://www.openstreetmap.org/browse/way/194871624 which has since been retagged (because the road reopened) and now displays correctly in the renderer. Version number 5 of it was the last one that had problem.

from #234, I'm seeing the pattern that all of these ways have: highway=construction AND a surface=paved tag.

@mkoniecz ; could you see if there are any highways near you that have highway=construction and a surface= tag that is not paved? This would be really helpful to narrow down the actual cause of the problem.

Unfortunately no, roads under construction are rarely tagged in my area.

This would be really helpful to narrow down the actual cause of the problem.

@skorasaurus AFAIK the problem is that unsupported values of highway have the default line color, which is black.

Now two things:

• it's possible that some of those "unsupported" values should be supported, so we need to add a color for them
• maybe have a lighter fallback than black; but maybe not, at least we see it, and often it means a wrong value, so it can be investigated and fixed quickly by editors

I'm planning a HDM work session very soon, so I may tackle that.

Closing in favor of #234
