I dunno, I don't buy the isn't necessary. People point to the 80,000 car cap at the tunnel as if that is the maximum capacity so there aren't more cars/trucks. The truth is the 80,000 is the maximum capacity of the Tunnel per day given commuting habits. It can't have more. So it peaked a long time ago but I'm pretty sure the demand is higher than that. You'll likely see after the bridge is complete the numbers jump up.
Quickly? No will be like the PMB when every toll-bypassing idiot goes and parks on the Alex Fraser Bridge for 2 hours a day just to avoid $3. But after 3-5 years I'd but money down you'll see crossing numbers jump up above 100,000 easy.
As for the 5 lanes, we're all entitled to our opinions. They did investigate an 8 lane option and as stated in the review, felt that the cost-benefit-analysis resulted in 10 lanes being more economical. You have to weight future proofing a bridge since you can't just magically widen it like a highway.
Bridges are bottle necks. Eventually HWY99 SoF will likely need to be widened to the same width as HWY 1 (3 general traffic + 1 HOV). An 8 lane bridge would then become a bottle neck again, so they are going 10. Without seeing the costs I doubt it was a huge amount more. $250 million maybe if that? That's peanuts.
Even an 8 lane bridge would be north of $3 billion because it has to be so high and so long given the Fraser River's width at shipping requirements. The Fraser at the point of the tunnel is nearly double the width of the Fraser at the AFB.
Finally think about the logistics of 10 lanes and to me it just makes absolute sense.
1 x HOV lane - This is definitely needed as it serves as a Bus lane. Encourages HOV traffic to reduce cars overall and allows transit (BUS/LRT/Whatever) to be predictable and more attractive for riders.
No brainer.
3 x general traffic lanes. So here I think we can agree because the options were 8 lane bridge or 10 lane bridge.
No brainer.
So the debate is that last lane and is it justified. I think it is. Why?
1) Right now through the tunnel in rush hour we have 3 lanes of general traffic. Yet it backs up for 2-3 KM+ every day. Why is that?
2) That is because this is a major transportation corridor and you have a lot of trucks. The tunnel is a reverse bridge meaning it goes down then up vs up then down from a truck-climbing perspective.
3) So with 3 general lanes you in effect lose 1 lane to trucks lined up crawling up the incline.
Therefor, other than the HOV, a $3 billion 8-lane bridge would not really improve HWY99 at all.
Instead with a 4th "climbing" lane for trucks, you get 3 full flowing general traffic lanes and the trucks climbing up slowly are in the 4th lane not impeding anyone.
Just makes sense to me.
But anyway you and others are entitled to your opinions and thoughts. I just happen to think for me it makes perfect sense and is a no-brainer.
