Reply to comment by drunkenknight9 in 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. by triviafrenzy
It was the furthest there are big dams on the Missouri now that block larger boats and barges from moving down the river, kinda a shame since it would be a lot more efficient then using trains to move all that grain from montana and the dakotas to port.
