Still, to this layman it seems like a colossal engineering cost to build all those bridges and ramps for relatively modest gain.
Stack interchanges increase acheivable throughput because you can often build enough road to allow backups for one direction to not impinge on the other flows.
It's also easier to build effective signage so there's fewer surprise lane changes.
In fact, the TFA goes further than your wiki skim to add that the merging from the highway to the clover leaf requires slowing down on the highway while entering the highway from the clover requires accelerating. Both of these things are being done in the same piece of road. It does so with graphic animations. You'd probably enjoy the TFA
Alternative responses are as simple as "thanks" or "you are correct, of course"
So it is to everyone's benefit to correct spelling and grammar errors. People learning English, kids, whoever... they all benefit from seeing correct language. Lashing out against it is infantile and counterproductive.
Instead, please consider helpfully linking to the animations[1] you're talking about, so that others can find them without having to waste time listening to content they already read.
At a cloverleaf, the weaving between people entering a highway from one leaf and people trying to get onto the next leaf is an utter destroyer of traffic flow, especially when you add in some human behavior, where some people are assholes and won't let people merge in front of them, even when they're trying to merge to the other lane themselves.
Many highways otherwise would have much more capacity. The telltale sign of exit issues is highways that bog down to 15mph for a couple miles, only to open up to 60+ with the same number of lanes.
Total shame and often unnecessary. I wonder how many man-years are wasted as a result.
there is also the weave required between exiting off a loop and other traffic entering onto it. you could theoretically get rid of it by bridging one loop over the other but then you may as well just bridge more of it without the 270 degree turn at that point.
and there are also compromise designs like the cloverstack where only two opposite sides are the 270 loops to avoid the weaving problem.
IMO, maybe Texas does this because Texas gets a lot more taxes than they talk about (through high property taxes), and don't really want to spend them on anything else (like socialism!), so instead they build 10 lane highway systems for the billion cars and trucks every american should own.
Another third comes from revenues from oil & gas.
About a quarter comes from state gasoline sales tax and registration taxes.
So a little more than 90% of the funding for freeway projects in Texas comes from non-property tax sources.
But even then, a lot of the recent major highway projects in Texas had some kind of toll component to them whether that just directly be toll roads or tolled "express lane" projects which often have parts of those toll revenue backed bonds going to fund things like highway interchanges and on/off ramps for the freeways.
The vast majority of the property taxes I pay go towards the schools, the public parks, the fire/police/public service, libraries, and local roads. City+County taxes are ~0.710%, just the ISD and community college is ~1.16%. A massive chunk of those city/county taxes are roads and public service people, with a bit of parks department and other things like that thrown in.
The state gets its cut mostly by sales taxes though. 6.25% is the state sales tax, with things like groceries exempted. Cities can levy up to 2% additional, for a max rate of 8.25%. Of that 2% my city levies, half of that goes to public transit.
In areas where large highways were built over small highways, it isn't so easy to add an additional road.
