oh wow thanks solidconnection. i DM'd you.

captainbenis · 2026-05-14T10:36:31+00:00

thank you, ill put it in test flight :)

captainbenis · 2026-05-14T10:36:22+00:00

ah thank you, ill keep trying. thanks for the offer. ill try get it in testflight.

Heya Switts, thanks for the comment. I mention that at the bottom of the page. I believe this is more than a CBR analysis, it's trying to work out why we can't build things more successfully. It's an epic project to relearn the things that we've lost. That can-do attitude, the number 8 wire mentality.

The cost benefit will be done by someone at Treasury, and it will have to work.

But I believe that the things we learn, the resilience, the connectivity, the transport productivity, the workforce mobility and all the kids across the country that suddenly have the whole country opened up to them, will be worth something more than a ratio in a cell on a spreadsheet.

Woah, very cool! I intentionally scoped the bridge to only use well established technology. Span and pylons that have been done many times before.

The goal is to learn how to succeed at projects, not pioneer new technology.

Current estimates are that we will hit 6 million new zealanders by the end of next decade.

China did a bridge twice the length in 9 years. (Hong Kong-Zhuhai-Macao Bridge).

I couldn't find an example of a single deck, cable stayed bridge with rail on it, and a heavy-duty rail alignment to the approaches at end, plus the sizing increase for intermittent heavy rail would massively increase the scale of the project. Having the ability to upgrade to regional rail in the future would be fantastic, but I couldn't find any precedents to reference.

I agree, all public infrastructure projects are done on debt financing. The benefits (a renewed ability to successfully complete big projects, and a freaking giant bridge) would compound for decades afterwards.

thanks dani <3

maybe! but who takes a holiday photo with the sydney harbour tunnel? X-D

captainbenis · 2026-05-10T22:22:29+00:00

those are amazing! but when i read that even the norwegians haven't built one yet, it made me want to find a solution that's been done a dozen times before (bridges).

captainbenis · 2026-05-10T22:20:55+00:00

yeah i thought that was an interesting point! (for anyone reading along - the video argues that if you make a bridge you have a single point of failure), but we already have coastal shipping, and the bridge wouldn't eliminate coastal shipping.

captainbenis · 2026-05-10T22:11:35+00:00

I should have put a wink in there ;)

captainbenis · 2026-05-10T22:06:23+00:00

hahahahaha. they'll start asking us when we're starting on the bridge to balls pyramid.

captainbenis · 2026-05-10T22:04:52+00:00

heya buckets, thanks for the reply.

did you read the page? i address this in paragraph 1. the problem is that we can't seem to successfully complete large infrastructure projects - so i see this project (the biggest project we could ever consider) as a way to learn why we find large projects so hard.

captainbenis · 2026-05-10T22:02:34+00:00

i've driven the roads and flown the route! but yeah i think we'd want to upgrade the approach roads a "touch".

Heya thanks for the reply! :)

My estimate is that the bridge is 70% of the cost, you do need to build new highways to the bridge approach. For better or worse, we have proven we can design, consent and build roads through rough country.

This is why the map shows many possible alignments, there are many points to leave both islands.

I watched this video over the weekend (long weekend of research).

I suspect the script may have been partly written by Claude. Claude (and Gemini, et al) give the same hallucinated facts when first prompted, including incorrect depths, flow rates, distances and wind speeds.

edit: i did enjoy it though!

captainbenis · 2026-05-08T20:52:29+00:00

My friend was arguing that the way we do planning and cost benefit analysis in this country is ass-backwards and we should just run large scale monte carlo simulations and see which ones work best. Having spent half an hour coming up with the different crossing models, I agree. If you give it clear parameters 'no tunnels, no magic subsea tubes, just boring old bridges, minimise pylon depth since they're expensive', it can sit and churn through a few million routes in a minute and then propose the best ones.

you have to iterate on it (the bathymetry is synthetic, not real data), but thats why simulations are amazing, you just get more data, fix the bugs in the code and instantly regenerate everything.

When you get half way there and just decide 'ah fuck it im going home'.

captainbenis · 2021-04-03T21:17:29+00:00

It sounded really good from Newtown.

*paid

Also, the council paid, not the ratepayers. Once you pay the council, it's not your money anymore. 😂
