The Saint Lawrence Seaway Development Corporation plans to solicit proposals for Project Management and Construction Inspection Services for a project to replace the existing electro-mechanical operating machinery with hydraulic machinery to operate the north side filling and emptying valves at Eisenhower and Snell Locks in Massena, New York. The project will be completed approximately between January 1, 2011 and March 11, 2011 while the locks are closed to navigation. T
