The U.S. Army Corps of Engineers, Detroit District, announces a contract award to replace aging equipment on the MacArthur Lock in Sault Ste. Marie, Michigan.
The more than $7 million contract was awarded to Ryba Marine Construction Co. The contract (award number W911XK20C0020) was for $ $7,276,650.00 to replace the World War II-era tainter valves for the MacArthur Lock. Tainter valves are used to control the flow of water used for raising and lowering the water level in the lock during a lockage. The MacArthur Lock has two sets of tainter valves, one upstream set and one downstream set.
“The Corps takes pride in performing maintenance to keep its existing facilities operational for long durations, while simultaneously planning for replacement and renewal as required to ensure the locks remain a resilient link in the Great Lakes Navigation System,” said Kevin Sprague, area engineer, Soo Area Office.
