Since the soil supporting the bridge foundations has exceptionally low load carrying capacity, it was important to reduce weight of the structure as much as possible.
Therefore, the design employs two weight-reducing elements: longitudinal steel girders and piers with cap beams at varying heights.
[3] The design of the pier foundations was further affected by the fact that the valley is a high quality agricultural area that had to be preserved as much as possible.
The superstructure consists of two longitudinal prefabricated girders of constant depth set 550 centimetres (220 in) apart made composite with the deck slab and cross-girders.
Structurally, the superstructure is a 1,354.86-metre (4,445.1 ft) long continuous girder across 22 spans, tracing a horizontal and a vertical curve.
