The only thing that jumps to mind is Bathurst from Lakeshore to near Front, when they rebuild that bridge over the tracks - which isn't much, but there often seems to be more congestion there, than anywhere else on Bathurst when I use that route.
That would certainly make sense. Might as well put in a dedicated ROW where they can, especially if it's a choke point on the route. There are very few places where this can actually be done in downtown.
