I have a better idea: drop the highway portion and build only the high-speed rail infrastructure. It's time we began supporting rail over motor traffic in a big way.
However though I am no fan of sprawl I suspect that the state will be better off with the TTC than without it.

I am yet to be convinced that long-haul passenger rail is ever going to be viable in Texas. (See AMTRAK...)
Further, I know that routing freight rail lmmediately alongside road traffic is a disaster waiting to happen. (See recent Kentucky train crash/fire...)
Utility lines and pipelines should not be placed in a restricted-access corridor. They should run (as they do now) across country -- directly to where their products are needed -- so that the leased land can continue to be crossed -- unimpeded -- and can (still) be used for agriculture/grazing. (Also, imagine the impact of downed high-voltage power lines or pipline blowouts/fires on the TTC...)
The multi-use, restricted-access TTC design concept of RINO Ricky and his r*mp-swab, Ric W. makes zero sense to anyone who is knowledgable in interconnection theory and practice. And it is a land-use and economic disaster.
I have an even better idea...Perry can give back the funds they looted to divert to other projects that was originally intended for overpasses and use it for it's intended purpose. IMHO, high speed rail will never be accepted by the common folk in Texas.
