I was immediately sucked into the Strands of History site via Colossal/My Modern Met. From the labor involved in prepping the ropes before cutting to avoid unraveling to the difficulties of then cutting steel ropes without the smaller wires vibrating… to the diagrams of the signature lays for the Golden Gate and George Washington Bridges?! I’m hooked! I truly hope I’m not the only one crossing my fingers that 99% Invisible will someday release an episode or a mini story discussing ALL that is involved in bridge rope/cable design. I have so many questions!
From Strands of History:
Below are figures to illustrate the unique lay of the vertical suspender ropes from the George Washington Bridge and the Golden Gate Bridge. Both of these bridges’ original vertical suspender ropes were manufactured by the John A. Roebling’s Sons Company (as was the Brooklyn Bridge, but we haven’t found that diagram yet).
Read more from Strands of History, and while we’re talking Roebling and bridges – read more about the Roebling Bridge/Roebling’s Delaware Aqueduct that was originally part of the D&H Canal.
