I was at one of the Broadway meetings before the summer, and got the impression from one of the facilitators that these meetings were one of the necessary steps in appearing to listen to the public on their desires for the UBC line.
My impression is that the decision has already been made to use SkyTrain Bombardier technology like the Evergreen Line. The Millennium line will be extended west overhead from VCC to Prince Edward St, then underground heading south under Prince Edward St to either 10th Ave (the preferred route) or Broadway, then continue underground heading west to UBC.
With the fiasco of the Cambie Trench they will be required to use TBMs instead, but one of the experts said to me "any decision made by a previous city council (to ban cut 'n' cover subway construction) can be changed by a future council"
The experts apparently have been busy analysing the public comments and ideas, and there will be another round of public meetings starting in Sept that will conclude with a preferred choice and cost estimates that can be presented to all layers of gov't for their approval.
I'm not expecting a UBC line decision to be made by the politicians before 2015 (so they can see the good or bad results of the Evergreen Line), with construction to be done by 2020.
By 'construction' I expect it to be broken into three phases:
a) VCC to City Hall;
b) Extension to Arbutus;
c) Extension to UBC.
with only (a) operating by 2020
