This paper describes the cable stressing sequence for an asymmetrically rock anchored cable stayed pedestrian bridge at Tshelimnyama. The bridge crosses the N3 highway near Durban and was built for the South African National Roads Agency SOC Ltd (SANRAL). During the construction period various stressing sequences were analysed with the aim of limiting the erection engineering effort and the construction risks. The final solution was found after a number of iterations and used the structures’ self-weight to partially stress the most critical cables. Importantly this limited the forces on the temporary support cables and reduced the jacking forces needed to stress the permanent cables.
