The 1950s Granville+Street+Bridge (GSB) should have at least had a provision for a lower deck.

A lower deck would have been great for extra bus lanes and potential LRT, but this is backwards BC.

Since no bus & bike bridge was even built right next to it, the bridge is being scaled down to 6 lanes, from 8. That might not have been necessary if there was an Oak Street Bridge (OSB) over F. Creek, not just over the Fraser River. An OSB over F. Creek could have been a bus & bike bridge with wide sidewalks as well.
The 8 lane GSB becomes a revamped 6 lane bridge with 2 bike lanes & 2 sidewalks.
If the bridge eventually has 2 express bus lanes, there will only be 4 general traffic lanes.

Unfortunately, the 8 lane Granville_Street_Bridge_(1954) wasn't designed to have a lower level. That wasn't the case with the 12 lane Ship+Canal+Bridge in Seattle. Fortunately, the Vancouver bridge was never connected to a city freeway, where as the Seattle bridge was. Vancouver should have opted for a better major street & bridge arrangement.
