Lake Champlain Seaway

The Lake Champlain Seaway was a canal project proposed in the late 19th century and considered as late as the 1960s to connect New York State's Hudson River and Quebec's St. Lawrence River with a deep-water canal.

[1] Though supported by business groups in New York and Quebec, it proved economically unfeasible.

Prohibitive costs (estimated at $100 million in 1900),[1] opposition from railroads,[2] and the diminishing utility of canal transportation prevented the project from advancing beyond the early planning stages.

The Great Depression cut the project's planning budget, while World War II and completion of the St. Lawrence Seaway delayed matters.

The growth of road and air transportation reduced the need for a canal, but the project was still under serious consideration as late as 1962.
