Is that a motorway for 25ft? ;) I think that motorways need to be relatively long. At least a number of miles of solid motorway to *be* a motorway. -- Dave ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us

Agreed. IMO, what downgrades a motorway to a trunk is the presence of anything that stops traffic on the main roadway for intersecting traffic (signals, stop signs, or yield signs). Really, anything more than just a very occasional road intersection that does not occur via ramps, or driveway, should be grounds to call it a trunk (or even lower). In the example, I'd call US41 trunk from Monroe St down to Waldron Dr, and motorway above and below that (at least for the area I looked at), simply based on the appearance of ramp-style intersections vs. traffic-signal-controlled perpendicular intersections. I'm guessing that speed limits would give further justification. -- Alan Mintz alan_mintz+...@earthlink.net ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us

Somebody could take you at face value and suggest that on the wiki. I think that motorways need to be relatively long. At least a number of miles of solid motorway to *be* a motorway. Exactly.

[Talk-us] National Forest signs
How should one tag the name signs at the entrance to a national forest (e.g. http://sites.google.com/site/am909geo/osm-1/DSCS5938_small.jpg?attredirects=0d=1 )? boundary=national_park is an error according to JOSM rendering rules. landuse=forest renders and icon in JOSM, but I thought landuse=* was generally for areas? -- Alan Mintz alan_mintz+...@earthlink.net ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
