And so it's much easier just to go up.

It makes, particularly over the past, we're moving away from the car and being dominant in the inner city.

But in the 60s to an extent, but the 70s, the 80s and the 90s, you really, you couldn't build an office tower without having car parking for workers underneath it.

So in that case, you just had to bite the bullet and do it.

We have better technology to do it.

And also some of that has turned into, you know, as people are taking public transport more, working from home, we tend to get more public parking in those.

So if Sky City's got an enormous underground car park, because they can make a big chunk of money out of that.

They're not just making money on the surface, they're making money underground.

Yeah, so even they had problems with the ground conditions.

So the Waterview Tunnel, for instance, which I was involved with further over, they had to dodge a few volcanic reefs there.

With the tunnel boring machine technology that we've got these days, though, it's much easier to do tunnels like the single rail link.

And we also have underground tunnels

the central interceptor going in, which will channel stormwater that's being bored.

And there is also a big electrical tunnel that you can drive down and a little kind of a jeep-like thing that runs electricity into Auckland.

No.

We also have pumps these days that makes life a bit easier.

So you imagine if Waterview Tunnel was open at both ends, imagine, and it dips down, so you can imagine that you'd need to get that water out of there if there was some disastrous cyclone or something like that.

Yeah.

Yeah.

So down in the viaduct area, there's a apartment building that's about six stories high.
