Freebeer, the source for this one was TIGER2017. It seems to be pretty consistent with the direction naming in this area. So I don't know why this road in particular would be messed up. Also, I did a lot of lot of looking around at other roads in the area, AZ in general, and also did internet research. What I found is not all roads have the direction in the name. Especially a smaller one like this that's pretty much a dead end service road. In fact, the street map of Gilbert from their website shows a bunch of roads that don't have the directions in their names https://www.gilbertaz.gov/home/showdocument?id=2320 Not that I don't trust Jon Hanson, but I have no reason to doubt the combination of TIGER2017, the Gilbert city map, and the other research either. Personally, I think he is just assuming all of them have it because most of them do. Which is understandable, but clearly incorrect. Also a lot of the roads on the ArchGIS website don't have them either http://tog.maps.arcgis.com/apps/OnePane/basicviewer/index.html?appid=f2cd965aaa424d1f80d854ad57ffa5d8
