Please not. But maybe underground, then yes, sure why not.
> removing a major thoroughfare, essentially to spite drivers)
I don't really know the particular situation. I hope it was not out of spite! That'd be sad. (I do understand fwiw - how it can come across like that). I do think a city should never accommodate high speed traffic, only maybe on an interstate or a truly segregated roadway. A lot of these high-speed corridors are through residential areas, it's just plain dangerous, noisy, polluting. There's a reason nobody wants to live next to a high speed road, and if they do, it requires a lot of empty buffer space (huge front yards, basically) to make it tolerable.
> lower throughput highways
Again, not knowing the particular situation, since this can be very context dependent, and maybe we have radically different examples in mind, so ymmv, fwiw, etc... Just as an example: in my town, a recent a high throughput highway was reduced from 4 to 2 lanes. That did not reduce throughput. It did decrease top speeds, no more mad max style passing and jostling, and fewer accidents. Basically, cars now toddle along in single file, at a civilized clip, but no longer that accordion of rushing and breaking from light to light anymore. It also is so much safer for people crossing the road, or biking. It took decades to make this happen. When trying to get these, most drivers at these public planning meeting could just not imagine that removing lanes has any kind of net good. After two years now of this conversion, which is positive is so many ways (it does not even inconvenience drivers, only curbs their worst impulses), every other similar proposal still face this same kind of opposition. This mindset is completely ingrained to such a degree that it almost seems monomaniacal.
