The pylons are 254 m tall and were cast on-site, 4 m at a time using climbing formwork (jumpform). All except the foundations, which were prefabricated and then brought on site. The suspended road, 2.7 km long between concrete anchor blocks, is made up of steel sections, held with high tensile cables.
