Flathead Tunnel
The Flathead Tunnel, also known as the Breakfast Tunnel, is a railroad tunnel in the Rocky Mountains of northwest Montana near Trego, approximately west of Whitefish. Located on the BNSF Kootenai River Subdivision, it is the second-longest railroad tunnel in the United States after the Cascade Tunnel. Construction began in 1966 and the tunnel opened on November 7, 1970. It was built by the Great Northern Railroad as part of a new bypass of part of the existing route that had to be abandoned due to changes caused by the construction of Libby Dam. Flathead Tunnel The
