Yes, but it doesn't neccesarily have to be a tunnel now. Perhaps they should do the grading now, and put the road in the right place, ready to be covered up when the runway goes ahead. I imagine it would take a little bit of a different design then regular design.
Either that or build it like a detour road right now, and build the tunnel beside it later, but then of course, you have to pay for building the road twice.
It'll be a long tunnel, but it'll be relatively easy to construct, since it'll be easy to do cut and cover construction, since there is nothing around there, just lots of open space. No expensive long distance soil hauling to do. I wonder how deep they need to make it?
