I'm told that the all tunnel option is coming up again because the traffic studies which were commissioned in the last Council transit debate are looking like they will justify duckunders/duckovers at several intersections along the extension. The debate is, is it better to have the transit line continually changing elevation, or just be built all at one elevation.
This reality has always been there. If you go back to the old traffic studies in the original ECLRT EA, they painted a negative impact for left turns especially at several intersections. Those findings were kind of swept under the carpet when the EA was written up, and with McGuinty cutting the line back to Mt Dennis the issue became moot.
The interesting thing is that I have recently heard people who are involved in residents' associations out that way debating about an elevated alternative. These folks arent transit geeks per se and would only be commenting on that idea if somebody they were talking to proposed it. Anyways, the next reportback to Council will happen once the Waterfront report has been dealt with. We may have data to look at before too long.
