Description
Seven-mile tunnel built by Morrison-Knudsen for the Great Northern Railroad as part of a line relocation around the Libby Dam, which flooded the original alignment along the Kootenai River. Construction began in 1968 and was completed in 1970 when the Burlington Northern took over GN operations. Now part of BNSF's Northern Transcon and is used by Amtrak's Empire Builder twice a day.Facts
