Oak Street and Granville Street are both 6 lanes wide for most of their lengths. Thus, this is mostly a 12 lane street corridor and is much less disruptive than if a 10-12 lane freeway had been pushed through in the 1950s or 60s.

The yellow line is set for 3 lanes each way. However, if it was moved over 1 lane, then there could be 4 main lanes one way & 2 lanes the other way.
The Oak+Street+Bridge+and+Granville+Street+Bridge are still part of an incomplete corridor.
An improved 8 lane Granville+Street+Bridge with double-width sidewalks could have still worked, if there had also been a wide bike & foot bridge built next to it. Then, a roughly new paralel bridge next to the 4 lane Oak+Street+Bridge could have allowed for an 8 lane crossing there. Four lanes of Granville_Street southbound over the Fraser River and 4 lanes of Oak_Street northbound.
Unfortunatly 2 lanes were removed from the Burrard+Street+Bridge (BSB), 2 lanes removed from the Granville+Street+Bridge (GSB) and 1 lane from the Cambie+Street+Bridge (CSB). That didn't have to happen if a bike bridge was built next to the BSB and the GSB. While the east side of the Cambie-Street-Bridge has a nice, wide sidewalk, there wasn't enough foresight to also have a wide sidewalk on its west side. However, that narrow sidewalk could still be built out to be nice & wide so that the CSB can be restored to 6 lanes.
When a city & metropolitan region mostly has narrow bridges, removing lanes or not having enough is utterly foolish! Case in point... https://www.pattullobridgereplacement.ca Instead of 2 bus & 2 HOV lanes, everything will be initially funneled into just 2 lanes each way. https://www.pattullobridgereplacement.ca/about/projectoverview Two nice sidewalks & 2 nice bike lanes, but no emergency lanes or bus lanes, right from the start. Its another classic BC bottleneck in the making. Since the SkyTrain doesn't run on a 24hr basis, 24hr bus lanes are essential, but that would go against the congestive planning methodology that is backwards BC.
