Somewhere in between 1950 & 1960, the old Fraser_Street_Bridge should have been replaced with a new 4 lane bridge, with 2 very wide sidewalks for bikes & a future provision for 2 bus lanes. Unfortunatly, backwards Vancouver has always been a city without a proper big city vision.

Then, decades & even several generations later, any BC bridge that could provide 2 wagon-roads each way was even more amazing.

As usual, Vancouver & BC lost & messed up an opportunity to have 2 great new bridges.

Once again, the lack of a proper big city vision resulted in the inadequate design for the 4 lane Knight+Street+Bridge. However, it makes sense from a bottleneck planing mentality. Despite Vancouver being part of what is suppose to be a major port region and in need of proper transportation corridors, the Knight_Street_Bridge is a classic chokepoint.
Just because the Knight_Street_Bridge started out as a 4 lane joke, there immediately should have been 2 wide shoulders, which could have eventually become 2 extra lanes. Plus, there should have been a future provision to add 2 bus & HOV lanes. Two wide sidewalks & 2 wide bike lanes. However, that would go against the congestive planning mentality.
