New speed limit signs are going up in the River Valley.
The speed limit from the Oklahoma border to Little Rock is increasing to 75 miles per hour on Interstate 40.
The change was made in July but the Arkansas Department of Transportation (ArDOT) says the increase only takes effect once the new signs are posted.
Speed limits on Interstate 49 from Alma to Fayetteville will also increase. The speed limit in Benton County will remain the same.
