They say everything is bigger in Texas , and now it seems everything might be faster too. The House of Representatives in Texas has approved a new transportation bill, and it includes legislation that would allow the Texas Department of Transportation to raise speed limits to 85 miles per hour. The state's Senate is presently considering a similar measure.The DOT cannot simply go out and slap up a fresh new set of 85-mph speed limit signs. Both engineering and traffic studies must be done before motorists are given a green light to those increased speeds. Don't feel too bad for those speed-restricted Texans, though. 85 mph wouldn't be much of a stretch for Texas, since the state already enjoys 520 miles of highway with an 80-mph speed limit.[Source: Chron.com | Image: University of Michigan
