Someone might have been very angry with bike people and not with car, bus & truck people. The real problem is that so much of the older BC infrastructure just wasn't designed to be more of a multi-modal crossing.
The Ironworkers-Bridge is so narrow for a highway bridge in that location & wasn't designed for substantial future capacity. When it was initially designed in the 1950s, there was no concept to have 2 bus lanes, 2 truck lanes & 2 emergency lanes for a port city. Plus, at least 2 general traffic lanes each way & a provision for 2 train tracks. Thus, the 6 lane bridge is overwhelmed, because it can't do the job of an 8-10 lane wide bridge.
Since Granville+Street & Oak+Street are both 6 lanes wide, the Oak+Street+Bridge should have opened with at least 8 lanes, instead of 4. Plus, 2 wide emergency lanes & 2 wide sidewalks. There still should be a new southbound OS Bridge, but the city would be against it. A narrow 4 lane bridge just doesn't have the space & capacity for 2 express bus lanes, 2 HOV & 2 truck lanes. Apparently, it's better to just funnel everything into only 2 lanes each way.
The OSB should be twinned or replace with something like the Samuel-De_Champlain_Bridge in Montreal. The largest city in Quebec is allowed to have a nice wide bridge & long metro trains, because Quebec isn't bound by anything like the backwards BC mentality.

https://vancouver.ca/streets-transportation/granville-bridge-connector.aspx A bike & foot bridge should have been built next to it decades ago. Then the Granville Bridge could have 3 general lanes each way, plus a bus & HOV lane each way. Instead, if 2 bus & HOV lanes are designated, there will only be 2 general lanes each way in the downtown core.
The Burrard Bridge should have had a bike & foot bride next to it. Instead, it was reduced from a 6 lane crossing to a 4 lane bridge.
The very narrow Oak+Street+Bridge & the Knight Street Bridge, should have had bus & bike bridges built next to them decades ago.
Most bridges in Vancouver & the metropolitan region just weren't designed with that much future capacity in mind, especially for buses & HOV lanes. Thus, it's a travesty that by now, almost every crossing should have had bus & bike bridges built next to them.
https://vancouver.ca/streets-transportation/walk-bike-and-transit.aspx Unfortunatly, provisions for bus & bike lanes just weren't the thing to do several decades ago in BC.
A truck lane is just as important as a bus & HOV lane. That's because freight should be efficiently & easily be transported in any major urban region.
