What also needs to happen is a true alternative to the single occupancy vehicle through the tunnel, which means transit, and if transit is going to be an alternative then it needs to be given priority over SOVs, which can't happen with the current configuration.

This is why an 8 lane structure makes sense but a 6 lane structure doesn’t.
First, such crossings given their cost to build and footprints should not intentionally be engineered as pinch points.
An 8 lane structure is so so so soooooooo much more flexible and resilient when it comes to transit implementation (such as rapid bus) and traffic flow at the abutting interchanges.
6 lanes is far too restrictive for this crossing.
I want to see a proper rapid bus system in this structure (as was going to be done on the original plan) and 6 lanes will essentially make that impossible. Having general traffic still restricted to 4 lanes (now without a counterflow) on an entirely new replacement project will be a boondoggle and would surely have any government lose their next election.
This is not the Pattullo. This is far more important than just a local structure.
