Boozman, Cotton, Inhofe, Lankford Recognize 50 Years of Commerce on the MKARNS

Written by Press Release

June 8, 2021

WASHINGTON – U.S. Senators John Boozman (R-AR), Tom Cotton (R-AR), Jim Inhofe (R-OK) and James Lankford (R-OK) recognized 50 years of commerce on the McClellan-Kerr Arkansas River Navigation System (MKARNS). The MKARNS is a key inland waterway navigation system for freight movement extending 445 river miles from Tulsa, Oklahoma through Arkansas and connecting to the Mississippi River.  

“Over the last 50 years, the MKARNS has had a tremendous impact on navigation, flood control, power generation, habitat conservation and economic development in Arkansas and regionally,” Boozman said. “This ambitious and visionary project has resulted in an inland waterway that allows low-cost, fuel-efficient transportation for more than 10 million tons of cargo each year, connecting people and goods throughout the U.S. and to the rest of the world. I join my colleagues in celebrating this milestone and will continue working to ensure the corridor is functional and vibrant well into the future.”

“The MKARNS functions as a gateway from the Mississippi River through Arkansas and Oklahoma—allowing easy transport of goods and commodities,” Cotton said. “I’m grateful for the many Arkansans and Oklahomans who keep this navigation system running, and I look forward to many more successful years of service to come.”

“Since its creation, the MKARNS has promoted freight mobility, expanded agricultural exports and enabled the cost effective movement of iron, steel, and other products—empowering economic development and job growth across Oklahoma,” Inhofe said. “This vital economic engine and freight corridor was the largest Army Corps of Engineers civil works project undertaken at the time of its construction and is most deserving of celebration. It has been a top priority of mine to work with a vast array of stakeholders, including the five public ports, 50 private terminals and over 90 industries that use the MKARNS, to ensure our inland waterway remains a key navigation channel. As we look to the next 50 years of operations, we will work together to modernize and deepen our marine highway so it can continue to anchor economic growth and prosperity for the entire region over the next 50 years.”         

“The MKARNS is a key interstate commerce component to Oklahoma and the region, and its economic impact has been vital to Oklahoma businesses and industry for half a century now,” Lankford said. “We should continue to invest in infrastructure modernization in and around the ports and waterways, maintain any safety and security needs, and ensure workers have what they need to keep MKARNS moving forward and thriving for the next 50 years and beyond.” 


  • One June 5, 1971, President Richard M. Nixon officially dedicated the McClellan-Kerr Arkansas River Navigation System (MKARNS) at a ceremony at the Tulsa Port of Catoosa, Oklahoma.
  • The MKARNS moves, on average, 11 million tons of commodities worth more than $4 billion every year and supports more than 56,000 jobs, driving economic growth and efficiency for a 12-state region consisting of Arkansas, Oklahoma, Kansas, Texas, Colorado, Montana, Nebraska, Minnesota, South Dakota, North Dakota, Missouri and Idaho. 
  • In 2015, the Corps upgraded the classification of the MKARNS from “Connector” to “Corridor” on the National Marine Highway, designated the MKARNS as a high-use waterway system and labeled the MKARNS as Marine Highway 40. 
  • In addition to navigation, Congress authorized additional uses for the MKARNS, including flood control, hydropower, recreation, water supply and wildlife conservation – all of which continue to contribute to the economic viability of the MKARNS for Arkansas, Oklahoma and surrounding states. 
  • The Senate passed S.Res.195 last week to honor 2021 as the 50th anniversary of the MKARNS; to recognize that investments in our inland waterways system support our economy; and to commit to completing the deepening of the MKARNS to its fully authorized, 12-foot depth.
