I posted this in another thread, but noticed it would also be useful here.

The span from Lonsdale Quay to Waterfront Station would be at least 3050m long. Evaluating the above equation for d=1525m gives us a cable height of 250m. Add on the minimum height requirements for cruise ships (61m is the height of Lions Gate Bridge and that is even too small) and we would need a tower of at least 315m. The Shangri-La, the tallest building in Vancouver is only 200m tall.
Even if two towers were placed in the water, the free span would still have to be at a minimum of 1100m and therefore a tower height of 100m would be needed. To achieve that minimum span length those towers would have a 25m underwater portion. Closer than 1100m and the depth of Burrard Inlet extends up to 70m.
It's engineering challenges aside, I also think it would be incredibly unsightly.
