When this bridge in Fort Benton, Montana, USA was built 1888 it was required to have a swing span to allow steamboats to navigate. It was considered the furthest navigable point on Earth, more than 2,700 miles from the Gulf of Mexico. historicmt.org Submitted by triviafrenzy t3_zrakng on December 21, 2022 at 4:45 AM in history 152 comments 2,659
