Is the UR still open? I'd love to inquire about this route with waze staff as my efforts to find out what happened here
No, unfortunately all of the turn restrictions looked good, and no close segments on 12 Mile were anomalies like "toll road", so I marked the UR as Not Identified. Here's a permalink
to that intersection though.
One note on those two u-turns though. sketch had developed and tweaked an experimental convention for "Michigan Lefts" that we are working with in Michigan only, with our RC's knowledge. Here is some documentation in our wiki on "median u-turn intersections
". I did change those two U's to match that. All of this is a long-winded explanation for why two at-grade ramps now exist there in violation of the accepted standards... Those had previously been marked as no name streets instead of named ramps, so Waze's routing may have just seen everything on that drive as "12 Mile".
