Wow, in backwards Vancouver, or almost anywhere in backwater BC, just having 2 lanes each way is tough enough. A consistent 3rd lane each way could be for busses and a 4th lane for HOVs. Given that Greater Vancouver is supposed to be a major port region, several of the bridges should also have a truck lane each way. However, there is only one bridge in backwards BC that has 5 lanes each way.
https://en.wikipedia.org/wiki/Port_Mann_Bridge#New_bridge Unfortunatly, it wasn't designed to have a lower deck. Such a lower deck could have had 2 freight train tracks, 2 commuter train tracks and even a provision for 2 BRT lanes.
Essentially, in any proper big urban area, the bridges should not only provide at least 3 general lanes each way, but a bus and HOV lane each way. That's 5 lanes each way, plus on some crossings that are closer to port activity, there should even be a 6th lane each way. That's the case with the Sir_Leo_Hielscher_Bridges. Unfortunately, unlike Queensland, BC has been very reluctant towards bridge duplication or twinning.

While Australia has Melbourne, Sydney and Brisbane as its major Pacific Rim gateways, Canada just has provincial Vancouver, Victoria and Prince Rupert as port gateway cities.

The Port_of_Brisbane and the Brisbane_Airport are excellent port facilities in Queensland.

https://en.wikipedia.org/wiki/Brisbane_Airport#Rail Far away from the inept transportation planning in Greater Vancouver, Brisbane was able to do things correctly.
https://en.wikipedia.org/wiki/Airport_line,_Brisbane Unfortunatly, backwards BC just can't seem to properly plan big city type infrastructure.
The YVR-Canada_Line is a total embarrassment!
https://en.wikipedia.org/wiki/Canada_Line#Stations Not 150 m, not 100 m, only a 50 m level clarence was allowed for the stations. Even the first 2 Skytrain lines only have 80 m stations, when they should have almost been twice as long.
https://en.wikipedia.org/wiki/Canada_Line#Technology Aparently, the inept planning was due to cost saving measures. Thus, instead of designing the stations to be long enough to accommodate 5 car trains, they were only designed to ultimately have 2.5 car trains. Since 2009, the Canada_Line still only has 2 car joke trains.
The Tilikum_Crossing in Portland vs the North_Arm_Bridge between Vancouver and Richmond. The Tilikum_Crossing accommodates 2 bike lanes, 2 footpaths, 2 MAX-LRT tracks, 2 articulated_bus lanes and even streetcars can cross on it. Such a fine bridge just hasn't been allowed in BC.

Given that most of the bridges in BC are so narrow, there needs to be proper bus, bike & HOV bridges built.
Transportation infrastructure doesn't have to be such a sad joke in backwards BC.
