I don't understand why flagging part of the graph as "small element" prevent a route to be found. I would agree to a potential downgrade of small elements versus normal ones, but a route have to be returned when it exists, haven't you? > I'm not sure what's up with the turn icons in the debug viewer - make > sure you've zoomed in far enough, turn icons only show up from Z12 and > higher. > Yes, I look between zoom 12 and 14 Still no turn icons I'm wondering if it's only a display issue or a more serious problem in my data processing. Anyway, osrm gives me routes with turns and intersections so this sounds to be only a display issue. All the best François
