CONCEPTUAL DESIGN / SERVICES CARRIED OUT

Bridge deck constructed with pre-fabricated pre-tensed concrete girders, with pre-fabricated pre-tensed concrete panels and a “in-situ” concrete pouring of the remaining slab. Over the intermediate supports there is continuity pre-stress at the slab level. The deck is divided longitudinally in the half length of the viaduct and transversally for each of road-ways, in a total of four independent structures.
The infrastructure of each deck is realised with two piers with circular cross section and a superior beam forming a frame. Two kinds of foundations were used: pier-pile; and a longitudinal binary of piles.
The two abutments are spill through type, with great robustness, to allow the connection to the decks through hydraulic dissipating seismic energy devices.
