- TxDOT to raise speed limit to 75mph on 1,500 more miles of interstates in Texas.
The Texas Transportation Commission recently approved 75 mph designations for nearly 1,500 miles of interstate. TxDOT is governed by the five-member Texas Transportation Commission and the TxDOT executive director is selected by the commission.
The speed limit changes span 60 Texas counties making it the largest conversion since a new law was passed last year. The 82nd Texas Legislature passed and the Governor signed House Bill 1353 which allows the Texas Department of Transportation (TxDOT) to establish 75 mph speed limits on Texas highways providing speed studies show it can be done safely.
Since September, the agency has been reviewing existing 70 mph speed limits across the state to determine where a 75 mph limit may be safely posted. Four Central Texas highways were the first to see higher speeds after the new law took effect. Thursday’s Commission action brings the number of miles now zoned at 75 mph as a result of House Bill (HB) 1353 to 1,618.
TxDOT recommended to the Commission that speed limits be raised on segments of I-10, I-20, I-27, I-30, I-35, I-37, I-40, I-44 and I-45 after engineering studies showed that higher speeds could be posted safely.
Posting new speed limits on 1,500 miles of interstate highway is a major milestone in implementing the new law, said Carol Rawson, TxDOT Traffic Operations Division director. Motorists must continue to travel at the posted speed until new signs are installed, said Rawson. “The new speed limit is not official until the signs go up,” she added. “Texas’ economic strength depends on the efficient and safe movement of people and goods,” Rawson explained. “These new speed limits increase highway efficiency while maintaining the safety of the transportation system.”
TxDOT studies of speeds on U.S. highways, state highways, farm-to-market and ranch-to-market roads are still under way.
Prior to HB 1353, Texas had 1,445 miles of 75 mph speed limits and 521 miles of 80 mph speed limits on certain state highways. These speed limits were previously restricted to specific rural counties and highways located mostly in West Texas. Texas now has almost 3,600 miles zoned at 75 mph or higher.
New 75 mph speed limits approved Thursday are located on:
- I-10 — 289 miles across El Paso, Gillespie, Kerr, Kendall, Bexar, Guadalupe, Caldwell, Gonzales, Fayette, Colorado, Austin, Jefferson and Orange counties
- I-20 — 423 miles across Crane, Ector, Midland, Martin, Howard, Mitchell, Nolan, Taylor, Callahan, Eastland, Erath, Palo Pinto, Van Zandt, Smith, Gregg and Harrison counties
- I-27 — 109 miles across Lubbock, Hale, Swisher and Randall counties
- I-30 — 139 miles across Hunt, Hopkins, Franklin, Titus, Morris and Bowie counties
- I-35 — 106 miles across Webb, Medina, Atascosa, Bexar, Hill and Cooke counties
- I-37 — 130 miles across Nueces, San Patricio, Live Oak, Atascosa and Bexar counties
- I-40 — 166 miles across Deaf Smith, Oldham, Potter, Carson, Gray, Donley and Wheeler counties
- I-44 — 11 miles across Wichita County
- I-45 — 143 miles across Walker, Madison, Leon, Freestone and Navarro counties
