Current Economic Status

It is widely recognized in shipping circles that the Seaway is incapable of handling the ships now commonly deployed in international trade. The Seaway was built when 10,000 grt was still a large ship. To what extent must the seaway now be regarded as obsolete? Chicago can no longer be regarded as a deep sea port when most of the world's tonnage is unable to negotiate the St Lawrence, the Seaway and the Welland. Everybody got to be somewhere!

If the seaway is in use, it is not obsolete. Is its use increasing, decreasing? How much money do governments put into the system to keep it functional?

Cost of Maintenance

The drawing to the right shows the various components which eventually need replacing. It comes from a 2010 GAO (United States Government Accountibility Office) report. In this report T. G. Dorn itemizes what needs to be done to keep the locks functioning. For the 52 component projects included, total estimated cost was $186 million.DonaldRichardSands (talk) 12:30, 1 March 2013 (UTC)

"This presentation explains how building the St. Lawrence Seaway and allowing ocean freighters into the Great Lakes in 1959 unleashed one of the world's worst environmental disasters." Unfortunately it is a self-published work and cannot be used as a reliable source. Alexander's presentation provides some leads for building the article's environmental impact info.
