The speed limit on most interstate highways in Indiana is 70 miles per hour, but that number will soon vary in at least one location.

That’s because the Indiana Department of Transportation is experimenting with using electronic signs to vary speed limits based on traffic patterns or the incidence of road work.

The first signs will go up on I-65 between Edinburgh and Franklin, where road crews are currently patching and resurfacing the roadway.

INDOT spokesman Harry Maginity says speed limits there will be adjusted based on how well traffic is moving.

Maginity says the signs are supposed to cut down on the number of read-end and chain-reaction crashes that can occur when speeds are higher and reaction times are lessened as a result.
