usually two routable lines of top of each other don't matter at all. There can be up to 6 routable lines on top of each other without problems. Only if there are 7 routable lines on top of each other or more, there are problems. On 03.01.2013 14:15, Minko wrote:
I can reproduce the problem if I use the default line style file instead of my own line style file so it is a style related issue.
I think the problem is that a tertiary highway http://www.openstreetmap.org/browse/way/114405617 forms part of the square which is tagged as residential highway & area=yes. It is drawn first as tertiary highway and also as residential road, so two routable lines on top of each other.
The issue is gone when you use continue in the lines style: highway=tertiary [0x05 road_class=1 road_speed=3 resolution 20 continue]
I dont know exactly what the difference is but it solves the routing issue.

The bug isn't new, I found that even maps from May 2012 had the exact same problem at that road.
