On a recent journey through Belgium & Luxembourg I got a bad direction. Tavelling towards Luxembourg on the E25/E411 at junction 31 near Arlon the route instruction was to leave the E25 at J31 then take the slip road & re-join the E25. This was difficult because of the turn restrictions where the slip road meets the N82. I've looked on OSM but I can see no reason for MFN taking this route. It looks to me like it should have kept going on the E25. I don't know enough about the area to make any changes so I'm hoping someone can help.
Start point was 50.927627, 1.816000 Eurotunnel at Coquelles France. End point was 49.635567, 5.968199. Aire de Capellen South service area on the A6/E411 near Mamer in Luxembourg. However I've tested it using tools - calculate & it routed perfectly.
