The construction is never-ending and the signage is terrible. It is what it is, nothing they can currently do about it.
I can't wait to see how it is when it's completed. As an infrequent traveller to Toronto, I'm interested to see how much better it will be, for everyday commuters and people like myself.
At the present time, I avoid Union at all costs.
Yes, I have gotten lost in it more than once.
