Starting to work out some of the details for the central spine of the design.
The detail seen in image 1 is more rigid and as such, is less likely to twist due to moment. The detail in image 2 however is likely to be closer to the final design. This is due to the fact that the twisting of the steel cables will produce angles that will have to be dealt with by moving the anchor* rings in multiple directions.
* - I name these "anchor" rings since they anchor the spine to the steel cables. The resultant bridge is self supporting by virtue of the bunching and twisting of the cables, just as muscle tissue and plant cells are.
