Such a 12 lane river crossing always has the potential for bus & HOV_lanes.
The Sir_Leo_Hielscher_Bridges also form a 12 lane crossing.

Even though it would provide proper bus & HOV lanes, Vancouver is one of the most reluctant cities about allowing bridge duplication or twinning. Thus, everything is funneled into absurdly narrow bridges.
The old Fraser_Street_Bridge was never replaced with a bus & bike bridge. The Oak_Street_Bridge, Knight_Street_Bridge & the Arthur_Laing_Bridge are classic 4 lane Vancouver chokepoints. Unless new HOV & bus bridges are built, these 3 bridges will remain quintessential bottlenecks. The ridiculously narrow Lions_Gate_Bridge is a three lane joke. There should have been a bus, HOV & train tunnel built around there decades ago.
The Second_Narrows_Crossing is also too narrow to accommodate proper bus & HOV lanes. Thus, any new parallel train bridge should also have bus & HOV lanes. Otherwise, it will just become another SkyTrain-bridge.
Unlike stubborn Vancouver, Montreal was able to build the new Champlain_Bridge. Indeed, the New_Champlain_Bridge has 4 lanes each way & 2 train tracks in the middle.
Such is the gatekeeper mentality of Vancouver, a city that wants to perpetually excel in congestive transportation planning. Fortunately, this thwarting Vancouver mentality hasn't spread to most other cities around the world.
