I think a bridge would be next to impossible. The ramps on the North side would be insane to get them to meet up with Steveston Highway. One of the biggest problems with the AFB is the climb up from Nordel. A bridge at Deas Island would be even worse climbing up from Steveston.
With current technology we could build a much nicer tunnel which would be much safer, and I think it would be cheaper than a bridge. A bridge would need so much stabilization work done. Think what they've had to do at Cape Horn, but worse, and on both sides. If we build everything as close to the ground as possible, I think it would be cheaper.
We could also upgrade it in phases, resulting in a much less mega mega project. We can start by adding a new tube to the east or west of the current ones. Then when that is open we demolish and replace the other tubes. That way no capacity is lost during construction, and we don't need to buy up swaths of new land next to the tunnel for the new roadway.
I think the George Massey Tunnel needs a replacement (for safety and lifespan issues) and slight expansion. I don't think it needs something as radical as the new Port Mann Bridge. And the current George Massey tunnel is already better off than the old Port Mann bridge because at least the GMT has 3 lanes open in peak direction at peak hours, you can't say that about the old PMB and it equals the AFB. The real problem with GMT is reverse peak direction. 10 lanes would be more than ever needed.
