The railroad bridge may have been owned by a terminal railroad that allowed NYC, NKP and Pennsy to access the ore docks.

Movable Bridge News posted Photo taken by Douglas Butler (Movable Bridge News) in 2016 a Strauss Heel Trunnion Railroad Bascule Bridge used by the Norfolk Southern Railroad is located in Ashtabula Harbor, Ohio. |
This bridge is an early Strauss heel-trunnion design. And, unlike other early designs I have seen, this 1911 bridge has not been converted to Strauss' later design. (Update: The 1911 Bridge Hunter page for the Duwamish River Bridge was my source concerning Strauss' earlier design. )This early design has the machinery room on top of the movable span and the operating strut is fixed to the counterweight tower. By 1919, Strauss had moved the machinery room to the counterweight tower and fixed the operating strut to the movable span. Below is a closeup of the two bridges on the South Branch of the Chicago River that have the modern design. I highlighted the operating strut of the near bridge, which is closed, in red and the strut of the far bridge, which is open, in yellow. You can see that the strut comes out the back of the tower as the bridge is raised. That photo allows you to compare the modern design with the earlier design still used in this bridge.
In this earlier design, the strut moves into the span. And you can see the machinery house on top of the movable span.

Walter Gunter posted, cropped Recreational boat traffic. At one time there was a ship building yard just upstream of this bridge that is recreational boat dockage now. It's in the up position most the boating season as there is very little rail traffic out of the harbor yards now. Most materials are moved by trucks now. Operated remotely from a control center. Ashtabula Harbor was a sleepy Lake Erie port until 1873, when competing railroads finally connected it to the steel mills of Pittsburgh and Youngstown, Ohio. Within two decades, it had become the greatest iron ore receiving port on the Great Lakes. |
