There was discussion about this sort of thing on the Australian list some time back, although from memory it was more about what constitutes a bridge, I can't fully remember the outcome, but imho anything able to allow something as big as farm machinery or a person to go under a road would be a tunnel not a culvert. _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
