I foresee traffic chaos into the downtown core from the east and northeast as the cars funnelling down from the DVP will end up hitting a logjam of vehicles stuck behind traffic lights on the new Lakeshore Blvd. It will also bring more traffic onto Richmond.
Same with the commute going the other direction. More traffic and gridlock on Lakeshore/Adelaide/Queen/Dundas, etc ...
You can argue that it will force ppl to use public transit. But public transit is not a realistic option for most who commute by car. This will NOT take that many vehicles off the road. And tourists coming in from the east and northeast? What better way to deter them from enjoying our fair city than by having them sit for hours on the DVP because the most freeflowing section of the Gardiner was removed.
Dismantling the Gardiner = Severe traffic congestion = More idling cars = higher CO2 levels .... SUPER IDEA!
