I know Gordon Campbell likes to compare the gateway with the St. Lawrence Seaway, but I think Delta's issue is a little more modest. It's really about the negative effects on the community in terms of noise, congestion, and that kind of thing.
We are putting in some very substantial investments, particularly in the Roberts Bank corridor. When you look at the federal contribution plus the local contributions and provincial contributions, there's over $300 million being spent just on that corridor between the Roberts Bank terminal and I guess as far up the valley as Hope, to deal with the interchanges, to make sure we're getting rid of the at-grade interchanges, and that there are noise barriers wherever we can put them, essentially trying to ensure that the gateway is community friendly.
You can always say you can put the whole thing underground and spend $20 billion doing it, but that's not practical. What we have to do is look for the practical solutions that don't destroy the economics of the gateway but do in fact improve and protect the livability of communities, and we're doing that. You'll see, I think, more improvements in terms of the level of pollution, for example, from trucks as we upgrade and encourage some of the trucks hauling containers to use greener fuels, and so on.
