Ahem, Toronto. If you are a Toronto politician, and you know this to be factually true but are unwilling to lead because, well, you might not get on a key committee if you do, you need to give your head a shake and ask why you are in politics in the first place. No city in the world is rebuilding expressways. They destroy cities.
Never forget that when Seoul, Korea removed the Cheonggyecheon expressway in 2003, & replaced it with a restored stream & 1000 acre park in the city’s centre, not only did it transform the city’s public life & economic success, but the traffic got better.
The traffic got BETTER.
