https://marinas.com/view/bridge/nyuqv_Connection_Sough_Swing... I don't know if that's about the right place given the description of locations, but it claims to be open and the coordinates match.
I suppose it's possible that there's that much sag when it's opened, hadn't thought of that.
Does anyone know if this is an active draw bridge?
The bend in the vertical tension bars could be from a jacking/span lock system at the ends of the swing span.
Some of these old swing spans will deflect when they are opened with the free hanging ends dipping downward. When the span is closed a jack/lock will lift them back into place. This lifting could cause some odd compressive forces in the thin tension bar causing it to bend when the bridge is in the closed position.
Just a theory, from seeing other swing bridges.
Knowing it can opened adds to my belief that the distortions in the verticals may be the result of the span locking mechanism.
We have similar but not visible span deflections on the Umpqua River Bridge in Reedsport, Oregon.
