I don't see why it needs to be a bored tunnel. Essentially what they're doing is putting a road beneath a road, so why not a cut and cover tunnel?
Because we'd want any freeway grade road along there to be wider than Portrush Road currently is. Doing that you'd need to acquire property on one side or the other, and cut off everyone's driveway access while they dig out the road
There'd also be less disruptions to traffic on South Road.
Even with a tunnel, especially one that is 10.5km long, they're going to need to acquire some property still.
Will the tunnel have any entry/exit points along it's route, or just at either end?
Also, with modern tunnels and the safety measures built in, there'd need to be some above ground facilities and services built.
A billion dollars to acquire properties, or a tunnel. Personally I think if it comes down to cost, they wont do a tunnel but will continue the trench and acquire properties.
Politically, and what might cost the government votes and a second term in power? then they'll go tunnel, especially if the federal government is going to contribute a substantial amount.
Personally I'm hoping for a tunnel, that has some exit/entry points along the route, but I think a tunnel is highly unlikely.
