I'm completely for this. I think there is a lot of misinformation on these boards, so I would like to address each point:
1)
The Skytrain Guideway is the most obstrusive and would still remain. Yes it would still, but to call it the most obtrusive is ridiculous. The Skytrain guideway has a width of around
6 metres while the viaducts have a combined structural width of around
26 metres. If you include the unusable space between the viaducts, you are looking at
50-100 metres. You tell me which one is the bigger barrier. Even though the Skytrain viaduct would remain, it could easily be built over, like the Van City building.
2)
They would need to be build a tunnel or widen roads, otherwise where will the traffic go? While I do think that some roads may need to be realigned, I do not think that any capacity will need to be added or replaced. In cities where actual freeways have been removed, it has been anything but a disaster. Take a look at New York's West Side Highway or the Embarcadero Expressway in San Francisco.
In both cases when highways were removed, traffic on neighbouring streets stayed level or went down. (
There's a whole site with great examples)Why is that? Enough people found that driving that way was no longer worth it and chose alternatives. The same will happen for these 1 km long viaducts, with either Skytrain, bus or cycling.
The important thing is that people get around, not that people get around by car. This project will make that whole area nicer and more pedestrian friendly.
