Built as a means to prevent severe grades on either sides of the Sheyenne River, the Hi-Line Bridge was constructed in the early 1900s as a part of the Northern Pacific Railroad. It stands at 162 feet above the river bed and 3860 feet long. It is considered as one of the highest and longest single-track railroad bridges in the United States.

The Hi-Line Bridge became a vital part of moving supplies across the country, which is also one of the top reasons why it has survived the wars unscathed. It was heavily guarded in both World Wars, so it never really became a victim of any sabotage.

The Hi-Line Bridge is still being used today, mostly by BNSF freight trains.
