I would need a study on if this would negatively impact desert ecosystems or introduce invasive species, but otherwise it sounds pretty cool if we limit the size until it's about as big as the new Panama Canal expansions.
It's not like the number of communities measuring a hundred miles wide are many. Also, believe it or not, the USA has bridge building technology. Shocking, I know.
Luckily this entire swath of land is completely void of human and animal life and nobody will be emminent-domained out of their homes and livelihoods with little to no reward for doing so, and bridges are notoriously so much more permeable than plain flat land. I'm such a silly goose to not have thought of those things when I wrote that very serious comment about this very serious hypothetical 🥸
Would need Willy Wonka's chocolate factory to exist first for that to happen. After all, Snowpiercer is a sequel to The Great Glass Elevator. Charlie just changed his name.
Alright, I'll take you seriously, the fuel efficiency per weight is far superior over water and vastly superior per volume. Sorry if I've been a little short with people in this thread, but it's hard to take any of you seriously after that first guy suggested the canal would somehow displace millions of people as if it absolutely had to be routed in a perfectly straight line through major population centers. I wonder if the disconnect is that the European Mind cannot comprehend vast swaths of unprotected land being underutilized in the USA.
First of all, I'm american, I'm a woman, and just look at our highway system. Black neighborhoods were bulldozed and paved over with highway interchanges. Cities were destroyed and continue to suffer from their existence. St. Louis, Detroit, Memphis, Cleveland, Chicago, etc., etc., didn't happen because suburbs 'won' in the free market of infrastructure or something.
Remember 8 mile, that road you don't go past in Detroit? Hmm yeah I wonder how that happened if bridges/crosswalks are such a good replacement for infrastructure that doesn't require those things in the first place. Infrastructure can facilitate national movement but it can also stand locally as an impenetrable wall. Put as many expensive "gateways" up as you want, it's still a fucking wall. There's a reason rivers are used as division lines between cities, states, and countries.
Do you really think there's going to be a perfect route through ALL of that land and that avoiding population centers wouldn't negate its usefulness?
Edit: also "underutilized" is an insane term to use for land. Just because humans aren't utilizing it, doesn't mean that land is devoid of use by other life. There is an entire ecosystem across this country that shouldn't be disturbed if we can help it, much less a river be built through it. I mean come on, we have a mass extinction event going on right now, all the way down to the fucking insects that splatter on our windshields.
Here is an idea for you: Don't build a fucking canal through Detroit?
They didn't have to bulldoze underserved and impoverished neighborhoods to build a highway, they wanted to. They could have gone around. Imagine not trusting any profession because notable examples of people in that profession in the 1980s included a really bad person.
