Layers are only there to explain the relative heights of things when they meet. No harm will result from marking the ditch as layer -1. Whether or not it needs to be a lower number than that of the bridge is an unresolved question. > Should I use barrier=entrance on the node > where the ways overlap, bridge=yes on the bridge (which means splitting the > way for a very short bridge), both, something else? There shouldn't be a junction between the bridge and the ditch, so no need to mark anything barrier=entrance. Just mark the whole bridge bridge=yes. > http://wiki.openstreetmap.org/wiki/Image:IMG_6784.JPG > http://wiki.openstreetmap.org/wiki/Image:IMG_6783.JPG The path: highway=footway (possibly bicycle=yes) It then meets a bridge: highway=footway bridge=yes layer=1 Then another path: highway=footway Meanwhile, unconnected, but crossing the bridge: waterway=drain Not sure I'd even mark it "barrier=ditch" after all that. I'd also only specify a layer for the bridge, not the ditch/drain.
