8 many years later perform commenced on another tunnel that would hook up Grosse Ile with Canada. The Michigan Central Railroad previously had a bridge that linked Grosse Ile with the U.S. mainland. But expenses soared as unexpected limestone formations were being encountered. Once yet again, the tunnel project was abandoned.

When the Grand Trunk Railroad Tunnel less than the St. Clair river at Port Huron opened in 1891, Detroit businessmen who feared that shipping of merchandise would be diverted to Port Huron demanded a tunnel be built at Detroit.

The phenomenal progress of the automobile field right after the conclusion of Entire world War I brought on renewed fascination in a further tunnel concerning Detroit and Windsor.

But he did not go to God. In its place he went to New York and convinced an architectural and engineering firm that “it would most likely be six dozen Sundays or much more prior to the politicians would concur on everything, so how about having a flyer on this as a private challenge?”

The business, Parsons, Klapp, Brinckerhoff and Douglas, agreed to style and design the tunnel and ensure its prices. Detroit, New York and Chicago bankers backed the the project.
