McClellan-Kerr Arkansas River Navigation System (MKARNS)

The MKARNS provides navigation through Arkansas to Catoosa, Oklahoma, near Tulsa. In 2015, the MKARNS received the designation of Marine Highway 40 Corridor (M-40) through the US Department of Transportation's Maritime Administration (MARAD) America's Highway Program. 308 miles of channel are located in Arkansas and public ports are located at Pine Bluff, Little Rock, and Fort Smith. An estimated $5 billion in private investments have been made on the navigation system since it was opened in 1971.
