I looked back and didn't see this shared here. Steve Munro published it on July 12.
This is a proposed routing for a 504A/506 when there is construction at both Church and Carlton, and King and Sumach.
This looks like something that come out of the second teleportation device in the movie "The Fly".
There is apparently a problem with turning at Yonge and College that has caused that peculiar jog to Wellesley, though everything about it seems wrong. This route will be stuck in traffic and in long turning queues all over the place, especially with Carlton and Church closed, that whole area will be jammed.
