I think an important thing to consider when choosing the classification is that motorway implies that the road is completely unsuitable for pedestrian, equestrian, and bicycle traffic (often that traffic would be illegal). If there is a significant stretch (more than 2 consecutive interchanges) of continuous full control of access, or an official source (e.g. the state DOT map) shows it as a freeway, I'd tag those parts with motorway even if this leads to something disconnected from the broader "network." The trunk/primary distinction on the other hand is more a subjective call based on the importance of the route and how appropriate it is for through traffic over the "long haul" - e.g. a route that is the next best thing to a continuous freeway/motorway. Route 2 is clearly a major through route in Mass. so the parts that aren't up to freeway standards probably should be tagged as trunk. And the significant parts that are should be motorway. IMHO of course ;-) Chris _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
