Gavins Point Dam is just a little upstream from here. I did not see a lock in a satellite image, so the lift span must be a relic of the steamship days. And that explains why the span can be left down for pedestrian use.
"Built 1924; rehabilitated 1953; bypassed by
Discovery Bridge in 2008." The 2,887' (280m) long bridge has a 250' (76m) lift span. [BridgeHunter]

Looking closer, there are no cables or counterweights left on the towers.

DOT
This source specifies a length of 3,013' (918m).
When built, the lower deck carried a railroad. "It is today distinguished as the only vertical lift span in Nebraska and South Dakota."

Obviously, each deck carried a lane of traffic by 2008.
BridgeHunter says the railroad was Milwaukee and Great Northern. Great Northern seems to be a mistake. And the Milwaukee no longer crossed the river by 1955. The railroad that terminated at Croton was C&NW.

posted three photos with the comment: "The old US Hwy 81 bridge over the Missouri River at Yankton, SD. A double Decker that I have driven semi over several times. Southbound is a tight fit, northbound, on top, is a spooky ride."
