hot_rod: Sorta. The way I read it, the TX legislature passed a bill that says the absolute maximum speed limit allowable has been raised from 80 to 85mph.
All that does is give TxDOT the go-ahead to go back and re-evaluate roads that are currently rated at 80mph to see if they can sustain an 85mph speed limit. If they can, then TxDOT is free to change out some signs.
The roads that are currently set at 50, 55, 60, 65, 70, and 75mph are probably not going to change because supposedly those were already evaluated back when the maximum limit was pushed up to 80.
And remember, highways like I-10 and I-35 that run through any kind of city jurisdiction typically have a much more difficult time getting bumped up due to local complainers.
