A new KHC photo in BC was added today to the project website. It looks like perhaps the new 4 lane roadway will be built at a lower elevation.

I believe this will wrap up phase 3 of the KHC project. Leaving only the short but super expensive phase 4.
In some ways I'll be sad to see phase 4 get completed, since I'm sure the Bighorn sheep will no longer be visible. They regularly walk on and around the TCH there (in relative safety I assume due to the slow speeds). It's cool seeing sometimes dozens of sheep at a time - from babies to big horned old timers. I've even read reports of the sheep using the animal overpasses as they were being built lol. It's too bad there will likely be no room for a rest stop around the sheep cliffs to stop and enjoy the animals. There was a similar area in Banff with a lot of sheep, but you can no longer see them. (probably best for them, but being around people might scare away predators so perhaps they prefer non-hunting people around).
But like a previous post mentioned a 30 year delay in Quebec I'm afraid phase 4 might be in the same situation unless another school-bus accident triggers a politician to wake up. There is rarely a perfect time to start a project so the best time is usually right now - especially if you're already years or decades behind. I'm afraid we'll be seeing sheep on the highway for many many years to come (I hope I'm wrong - kind of hope anyway).
