Apparently, 2 of the 3 Skytrain bridges were never designed to also accommodate bikes.
Unfortunately, all 3 Skytrain bridges weren't designed to have any express bus lanes, never mind any for a proper rapid bus network.
In the 1980s, once it was revealed that Skytrain wouldn't be providing a 24 hour service, there wasn't a serious effort to convince the public of the importance of having a 24 hour regional express bus network. Transportation redundancy is difficult to grasp in backwards BC.
All 3 of there's transportation bridges should have had enough future space for at least a 3rd track. Upon opening, each bridge should have had 2 bus lanes that also could be for emergency vehicles. Each bridge should have had 2 bike lanes and 2 sidewalks.

It was never doubletracked and the interurban trams were phased out by the 1950s. Yet, most of the highways and general road system in SW BC cities are just 2 lanes each way. It was as if there was no need to have a 3rd lane for trucks and a 4th or 5th lane for buses & HOVs.

The transportation infrastructure was set up for congestion, right from the start. Having a short Skytrain & small stations might have made economic sense in its initial phase. However, there was a failure to not design it to eventually become a proper big-city size train with much longer stations.
