I think eventually most cars will continue along Bayview to Mill Street but the western section of this is still blocked off due to Pan-Am Games construction. Cars can then turn onto either Cherry or Parliament and both have, or in case of Cherry, will have, lights. Initially all traffic will be sent to the King/Lower River intersection from Lawren Harris Square. There are new lights at Lower River (i.e. River Street south of King) and King.
I doubt cars will be encouraged to go along (old) Eastern Avenue towards Front Street if they want to go west as the junction of Eastern/Front at bottom of the bridge will be hard to adjust. (Now cars cannot turn west there, legally anyway!)
