Late to the game but has decking been considered instead of tunnelling? Maybe less disruptive/expensive?

I have no evidence, but Ford did say "anything and everything is on the table."

Ford needs to appeal to his car loving base. Even the 401 widening isn't good enough for Ford Nation.

If Ford was more open to having another expressway parallel to the 401, and not being fixated on just the tunnel it would help his credibility. It would show that he's looking at other options to alleviate traffic in the GTA or the 401. I think more people would take it seriously and be more willing to bring in ideas.

But to have decade long construction project underneath the busiest highway is asking for it to be cancelled by any means necessary. And that's not including the cost and the eventual cost ballooning.

I actually hope Carney declines this request by Doug. That way Doug can either focus on other alternatives for the 401. Or he can look like a lame duck on the issue. The Sheppard line could save face if Carney declines. Which could be the blessing in disguise and a alternative.

Though what benefit would a suburban highway parallel to the 401 give to drivers heading to the city?

If the goal is to divert through traffic off the 401 and onto some other route, than there is the 407. Yes yes it's tolled but there are ways to mitigate that.

How much time savings would another highway in the north give. Say, for example if the 413 were extended east to the 412/407 junction. Would that really save time for someone travelling through the GTA?

At least a decked highway makes some sense. It is also expandable at a relatively low cost. My fantasy highway thinking is a decked highway that only has exits for other highways. That would really make it express.

Decking is really common in Japan/Asia. Also, does Ford see The Boring Company as doing this?!

I believe there was text somewhere about studying options. I have to wonder if expropriation and widening may be a cheaper way to add another 4 lanes.
