The Knight_Street_Bridge 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 incredibly inept Fraser_Street_Bridge 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. 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 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 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.
