Hi, thanks for your reply, I will keep that in mind with "only area at a time". I think the routing problem stems from the gate on State Route 148: if you open https://gpx.studio/app#13.65/37.59027/-112.85132 and start the routing at the "Cedar Breaks National Monument Visitor Center" the routing only works if you click on a point before the gate. If you try to route directly by clicking on "Cedar Canyon Road" it says that "the start point is to far from the nearest road". Not sure if that has anything to do with OSM though?
