Ok, I guess the big question is whether Ulster Ave should be split into a dual carriageway... Generally we only do this is there's a physical divider of some kind, not just road paint. (See https://wiki.openstreetmap.org/wiki/Dual_carriageway .)

If it *is* valid to map as dual carriageway (I was on Ulster Ave on Wednesday & I'm appalled that I can't remember!) then that has a lot of impact on what turn restrictions are necessary where. Eg, this only_right_turn that I added at the exit from Kings Mall:
https://www.openstreetmap.org/relation/14697083 ... it was useful when Ulster Ave was two-way, but exiting onto a one-way road it's redundant.

https://www.openstreetmap.org/relation/14697154 is even worse... it made sense when I added it, but now it applies to traffic traveling south in the northbound lanes, so it's completely meaningless.

There are also implications to the bus route relations... eg see how this bus route now jumps between the northbound and southbound lanes: https://www.openstreetmap.org/relation/12678504#map=18/41.96173/-73.99022
