The Fort Worth Star-Telegram has the story
The Texas Transportation Commission agreed Thursday to increase the speed limit to 80 mph on more than 521 miles of Interstate 10 and Interstate 20 in rural West Texas, through the Davis Mountains and toward the southern tip of the Rockies.
New signs could be posted as early as Saturday, Texas Department of Transportation officials say.
The 5 mph increase could theoretically reduce travel by 90 minutes between Kerrville, northwest of San Antonio, and Fabens, east of El Paso.
State officials say it's safe for drivers to travel up to 80 mph in the sparse, 10-county region where Texas plains turn to Chihuahuan desert.
This wil also speed up travel to Big Bend National Park, home to beautiful desert, mountain, and canyon scenery, and one of the best spots in North America for amateur astronomy.
