The way that this behavior was simplified is particularly restrictive as it was assumed that firstly, the footing bears none of the load and secondly that no skin friction is created along the shaft except in the case of tensile stress. To reduce the bearing size, spherical bearings covered with a new composite material to resist stresses up to 180 MPa under ultimate loads were used. To resist the high bending moments due to their extreme height, the piers were designed as wide strong box-sections that split into two flexible shafts in the upper last 90 m. The box-girder deck is tied down to the pier by vertical prestressing tendons in line with the two fixed bearings on each shaft, and the pylon above has the shape of an inverted V.
