I wonder what the practicality would be of, rather than having the LRT do a loop, simply build a little tram-like thing that ran along City Centre Dr to Confederation Parkway, then along Rathburn (hitting the transit terminal, and possibly even a relocated LRT transit terminal), then back onto City Centre Dr. It could even be a touristy type of thing, yet functional, like the San Francisco cable cars. That in my mind would be much more practical for thru-traffic then forcing a diversion around Square One.
