[Mister F]

An elevated second deck would be almost as bad of an idea as Doug Ford's fantasy tunnel. And equally ineffective at fixing traffic. The only reason that the 401 is the busiest highway is because of induced demand. We built all that capacity and travel habits adjusted to fill it in no time. If traffic is at a standstill with a 12+ lane mega-highway then it won't be any better with even more lanes. The strategy of building bigger and bigger highways has failed.

The 401 is already a bigger highway than almost any other city has, including much bigger ones than Toronto. The last thing we need is to make it even bigger. Ontario has made real progress in mass transit in the last 15 years or so. That's the answer to better mobility in growing cities.
