There is, except it varies according to the topography of where you're doing it. A rule of thumb is that a kilometre of highway generally costs you $1 million, but if you're doing it in the Rockies you throw that out, because it will cost you $30 million to $40 million a kilometre. If you're doing it in Kicking Horse Pass, it might cost you $80 million a kilometre. So really there is no general answer. It's very place-specific.
