The 2010–2013 Statewide Transportation Improvement Program from the
Arkansas State Highway and Transportation Department (AHTD) lists
cable median barrier installation projects along segments of
Interstate 30 (I-30),
I-40,
I-55, and
US 67 to begin as funds become available. The high-tension designs will first be installed in areas with narrow medians (less than wide) that carry an
average daily traffic of 15,000 or greater near sites of recent serious crossover collisions. ==Primary Interstates==
