Kentuckians will soon be enjoying life in the fast lane on most rural interstate highways and parkways.
A Kentucky Transportation Cabinet spokeswoman said the new speed limit of 70 miles-an-hour will take affect after signs are posted next week.
The General Assembly approved the higher speed limit in March 2007, but delayed its implementation until highway engineers could study the matter.
The engineers identified stretches where increased speeds would be safe and 496 speed limit signs will be changed.
The speed limit won't increase on urban stretches of interstate highways
