Aerial spinning techniques have generally been used for large suspension bridges only. This is due to the higher erection costs compared with the use of locked coil cables. However, due to the increased cost-effectiveness of aerial spinning in the last ten years, it was decided for the two narrow, intermediate span suspension bridges at the Triangle Link project to develop two cable alternatives for bid. Despite the fact that the cable tonnage for both bridges totally is as low as 2000 tons, the aerial spinning alternative was the cheaper alternative and thus chosen for this project. In this paper design aspects relating to the development of alternative cable configurations, their impact on affected structures such as saddles, splay chamber and anchorages are outlined. In addition comparisons of weight and costs are made.
