# List of Interstate Highways in Arkansas

The list of Interstate Highways in Arkansas encompasses nine members of the Dwight D. Eisenhower National System of Interstate and Defense Highways in the state of Arkansas.

## Cable median barriers

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, I-430, Interstate 540, and US 67 to begin as funds become available. The high-tension designs will first be installed in areas with narrow medians (less than 40 feet (12 m) wide) that carry an average daily traffic of 15,000 or greater near sites of recent serious crossover collisions.
