That’s the Williamsburg Bridge under construction circa 1902. I’ve discussed a similar construction picture in the past, including why I believe Williamsburg manages the difficult task of being an ugly suspension bridge. This angle is a bit different and shows more of the very deep stiffening truss. Only the land span of truss had been constructed at this point, but that exact same truss pattern was continued across the entire deck and is arguably more prominent than the suspension cables when you look at the bridge today.
This picture shows more than two spans of the land portion of the bridge, where the suspended side-spans would be on a more average suspension bridge. (Williamsburg has only the main span suspended, so the cables are taut diagonals from the tower tops to the anchorages. They’re not taut in this picture because they were loaded only by self weight at that time.) The deck hasn’t been installed yet, so there’s just the trusses and the deck beams, making the land spans into a gigantic cartesian grid.
