Speed Limits - 75 and 80 Mile Per Hour
As of September 2011, state law allows TxDOT to create higher speed limit on any state highway if found to be reasonable and safe through an engineering study. Each new 75 or 80 mph speed limit must be approved by the Texas Transportation Commission.
The tables below show approved 75 and 80 mph zones and are divided by the month in which the Commission approved the speed limit increase.
