I think your bridge will have to happen, as with a combination of the Gowland Range, and the Sooke Hills, almost all future densification will occur in the Collwood/Langford/Metchosin/Sooke area in the next 50 years.
Development isn't going to happen to the North of the city ... it can't ... there's nothing but mountains in the way. So it's going to go to the West, which is rural today, but can't remain that way based on the continuous development I've seen happen here in the last 50 years.
Although development may one day go up the Saanich Peninsula, for the time being the Agricultural Land Reserve protects a great deal of that land from development. And although there is ALR land in the Westshore (primarily in Metchosin, and scattered about elsewhere), it's far less a factor on the Westshore than it is on the Saanich Peninsula.
All this to say that in the next 50 years pretty much all new construction will occur on the Westshore (it's underway already) which one could anticipate will one day (50-75 years?) rival the Saanich/Victoria/Oak Bay triad for population density.
Weather, lifestyle, access to recreation 365 days a year ... it's been drawing a non-stop stream Canadians to live in the CRD for decades now ... and will continue to do so ad-infinitum.
So your bridge will have to happen - there really isn't a choice in the matter.
(Of course much driver suffering will happen in the meantime, likely for years - if not decades before this actually happens, and even with your new bridge, there will still be a need to some form of light rapid transit through the same general area).
Personally, I'll be long dead by the time this all happens ... but it would indeed be a sight to see!
