As of the imagery in NYS Orthos Online, construction was obviously in progress - and neither the 'construction' nor the 'motorway' in OSM lines up with what I see in the orthoimagery. I see that the DOT has the construction documents available at https://www.dot.ny.gov/regional-offices/region9/projects/prospect-mountain-route-17 . It's a complex project. The good news is that there are georeferenced plan views of everything. I can certainly see on OSM that the ways do NOT connect through there, and that there's a lot of overdrawing, including things like untagged ways. NYS Orthos Online clearly shows a construction zone, and I'm virtually certain that the current traffic routing is different from what I see in the orthoimagery. I think that taking this on as an ongoing project will be too much for me, and certainly untangling the mess that I see at the Chenango is too much for me right now - life is simply getting in the way of mapping. I think I'm going to have to bow out and let someone else give this a try. I have relatively little experience with freeway mapping; my chief mapping interest is outdoor recreation. For whoever is able to take this on - I definitely recommend using NYS Orthos Online for tracing. It's at least new enough to show construction in progress on the new bridges and the interchanges on I-86. Bing, Digital Globe, ESRI, and Mapbox are all hopelessly out of date.
