The Knight_Street_Bridge (KSB) was deliberately designed to not have a couple of emergency lanes. No truck lanes and especially no bus and HOV lanes. No proper bike lanes, just 2 narrow sidewalks.

Thus, the Knight_Street_Bridge is one of the best examples of BC bottleneck planning.

The Knight_Street_Bridge is so narrow and inept, that a new HOV, bus and bike bridge should be built right next to it. The Knight+Street+Bridge is only 4 lanes wide in the middle, so a parallel 4 lane bridge would greatly improve things. One lane on and one lane off between the twin bridge crossing and Marine-Drive. Then the main 3 lanes each way onto the 6 lanes of Knight+Street up to Kingsway.
The incredibly narrow Fraser_Street_Bridge (FSB) was torn down and should have been rebuilt or replaced by the 1970s, especially by the 1990s. The city and the Provincial_government didn't seem to understand that a new bridge there would be great as a HOV, bus and bike bridge. A couple of wide emergency lanes would have made it a lot easier for emergency vehicles to go between Vancouver & Richmond.
Despite Oak Street being 6 lanes wide, the BC bottleneck mentality wanted to force everything into a 4 lane Oak_Street_Bridge (OSB). Even if there was no concept to have bus lanes in the late 1950s, the OSB should have had 6 lanes, plus 2 wide emergency lanes and 2 wide sidewalks.

By now, there should have been a HOV, bus & bike bridge built next to the narrow & inept Oak_Street_Bridge.
The Arthur-Laing-Bridge (ALB) is only 2 lanes each way. https://en.wikipedia.org/wiki/Arthur_Laing_Bridge
The multigenerational inept Vancouver & BC planning agenda is all about creating more congestion.
Fortunately, the 8 lane Champlain+Bridge also has 2 passenger train tracks. This was possible, because Montreal and Quebec don't have anything like the Vancouver & BC mentality to hinder them.
Why have a provision for 10 car SkyTrains, when a 2-4 car joke of a train can enable more congestion? That's the backward BC way.
It's amazing that the Montreal+Metro was designed to have 9 car trains, even back in the 1960s. Montreal and Quebec in general, just don't have anything like a backwater BC mentally to contend with. Quebec isn't just able to do more because it has more people than BC, Quebec has been able to accomplish more because it isn't BC.
