That's my question. Is there such a thing as underground or over the ground technology—that's the technology I'm interested in—to avoid that problem? Quite frankly, I don't see how in any part of Canada you can, as a result of our transportation corridors, avoid these crossings without having investments.
Each one of these overpasses cost $40 million to $80 million. Given those kinds of numbers, there has to be some other technology that would make it cost-effective to do, such as underground or over and above. I'm not sure of that technology.
