The SkyTrain+bridges could have been designed to be proper multimodal crossings. Unfortunately, the BC way is to provide a half-assed attempt.
The Skybridge between NW & Surrey is one of the worlds best examples of inept urban planning. No foot & bike paths & especially, no bus lanes. Fortunately, the backward BC mentality wasn't able to reach & prevent Oregon from building the fantastic Tilikum_Crossing.
The first 2 SkyTrain bridges should have been designed to accommodate at least 3 tracks.

The first 2 SkyTrain bridges also should have had a foot & bike path on both sides.
Unfortunately, the North_Arm_Bridge for the Canada Line was also designed to not have at least 3 tracks & 2 bus lanes. There is only one combined foot & bike path, when there should have been 2. Fortunately, the Tilikum_Crossing's_Design allowed for 2 types of rail systems, bus access, with bike & footpaths on both sides. The Tilikum_Crossing in Portland is so well designed that such similar bridges should be built in Calgary & Edmonton, or even Winnipeg, some day.

Of course the SkyTrain always has the potential for higher capacity over the Edmonton_LRT, CTrain & MAX_Light_Rail, simply because its a fully grade separated system. The biggest mistake for the SkyTrain was that it wasn't designed to ultimately have a 152.4 m station, like the Montreal_Metro has.
