It is 568 metres long and 32 metres wide, consisting of 2 variable inertia contiguous mixed steel/concrete decks. These structures with 8 spans are supported by 2 abutments and 7 piers with their foundations on piles 1.60 metres in diameter between 22 and 31 metres depending on the support points.
The piers consists of 2 elliptical section drums.
