There is a server weirdness with their display properties, but the URs themselves seem to be "real" - we probably just got a bunch because the server processes batches, and just did our area - I'm looking at a lot in Boulder and up I-70, and cleaning up most of them.
Most are trivial, either an incorrect turn restriction, or one I know was fixed recently (and the UR processor uses historical data so it will sometimes throw an error even though the map was already fixed). Some are just areas where people are ignoring the directions, even though they are "legal". In these cases I gather it is best to just verify all the turn restrictions in the area, and then mark it "solved" and hope the routing engine adapts on it's own?
However, along I-70 there seem to be a lot of places where the routing engine was doing and "off and on", and people were rightly ignoring it. I'm hoping someone experienced with highways could take a quick look at a few of them to make sure there isn't something broken in the junctions...
Here is the permalink to the first one, and there are several more as you head East on I-70 toward Denver: https://www.waze.com/editor/?zoom=3&lon ... TTTTTTTTFT
