The Granville Bridge 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 backward BC.

Since no bus & bike bridge was even built right next to it, the bridge is being scaled down to 6 lanes, from 8.
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. The Vancouver bridge was never connected to a freeway, where as the Seattle bridge was.
