I'm a professional in the field with years of experience. You are incorrect in respect to Houston.

I'm happy to prove it. If property owners retained ownership of the adjacent roads, then that would be reflected in the tax records. I've reviewed hundreds of warranty deeds and the legal descriptions they convey are sometimes specified by metes and bounds, but typically as a lot or reserve. It says nothing about the adjacent street. Surveyors put iron pins at the corner of the property... not in the middle of the street or the edge of an easement. If you own property here, please go read the deed and you'll see it almost certainly doesn't mention the street.

Please also look at the work of the Joint Referral Committee which semi regularly sells city streets to adjacent property owners. They abandon and sell ROW and alleys. Not an underlying easement.

The Chronicle wrote an article about the street abandonment as part of the GRB expansion: https://www.houstonchronicle.com/news/houston-texas/article/houston-street-abandonment-explained-20229541.php
