A company that runs electric lines beneath the Straits of Mackinac says a proposed tunnel could be dangerous.
The proposed tunnel would house a replacement section of Enbridge's Line 5 pipeline.
But it could also be used to hold other utility lines, including electrical cables.
Tim Finco is with the American Transmission Company.
The Petoskey News-Review reported Finco wrote in a letter the company doesn't believe it's a good idea to install its high-voltage electric lines in close proximity to high pressure oil or gas lines.
