There was a push for something like that and it would have been great...it fell afoul of NIMBY and Toll road haters. https://en.wikipedia.org/wiki/Trans-Texas_Corridor Everyone in Austin hated SH-45 & 130 when they were built, they were practically empty for a few years to my delight as I could travel the entirety of Austin in a fraction of the normal time even during rush hours. After MOPAC was added residents began to see the light and the tollways are now congested. Many are regretting their opposition to Perry's lost/last road project but, that train has left the station unless Elon can get the Boring project going or Virgin is able to implement their version of Hyperloop. Hell, I'd have settled for elevated wire gondolas over the roads, works well enough for Australia.
