text: Someone added a no u-turn restriction on Rundlehorn dr - just east of this note - this prevents the OsmAnd's A* algorithm from doing the weird right turn onto Rundlehorn and u-trun, than back across 36th. I'm closing this without changes as I now think the issues was the OsmAnd's A* algorithm. 
  
  abDoug - interesting discussion on u-turns at the traffic intersections, reading the alberta road rules, u-turns are not allowed, so a routing algorithm should implement that without us having to add no u-turn everywhere.
