It depends on where you are. They let I-35 between Dallas and Austin get in really bad shape when Rick and Ric were trying to do the deal with the foreigners for the toll road network. When that blew up, they finally started working on re-building the Interstate. The parts they have gotten to are nice, but the construction is a mess. And the road through Austin will continue to be nasty, as they did get the toll bypass done, and they don't want to siphon traffic away from that.
The Republican areas tend to keep up with the local streets, the Democrat controlled areas are more selective as to who gets the good streets.
One thing that is terrible is the lane marking. They either use buttons with inadequate adhesive, or paint that quickly wears off. Don't bother with lane assist; you need visible lane markers for that to work.
