Arkansas River

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.

"It's a global marketplace. And Fort Smith is a part of it." – Asa Hutchinson, 46th Governor of Arkansas

In the late 1800s, the river base of Fort Smith was known as civility's last outpost before heading into the Wild West. Now, it's known as the location of one of this country's brightest economic revivals. By outworking cities from coast to coast, Fort Smith has dropped its unemployment rate threefold, partnered with several international companies, and is now planning for years of good fortune.

Meet the civic trailblazers and the economic development team who built on, and built out, Fort Smith's unlimited potential. And see how OG&E's multi-million-dollar grid program is a critical investment in our continued success.
