In 1961, work was begun on a new Poe Lock to handle ships up to 1,000 feet long with cargo capacities of more than 50,000 tons that were on the drawing boards.

By 2000, the number of passages per day at the Soo Locks had dwindled to around two dozen or fewer commercial vessels, and today the number of vessels in active service continues to shrink.

It would relieve the pressure on the Poe, the only lock able to handle vessels more than 730 feet long and 76 feet wide. Shippers have long feared a breakdown or accident that could disable the Poe, rendering Lake Superior ports inaccessible to most of their vessels. Cost of such a lock, estimated at more than $250 million, would be paid for by the Federal states the Great Lakes. Although numerous studies have been conducted, no lock construction has begun.
