- Structural work with a length of 275 m. Two independent decks with a total width of 25 m. Spans: 20.50+9x26.00+20.50. Girder deck solution with precast reinforced concrete girders h=1.50 m. Intermediate piles with a diameter of 0.8 m. Placement of viscous dampers between the deck and one of the abutments. Work carried out on a very deep landfill whose waste is rather aggressive for concrete. For this reason, the piles were protected with metal tubing, which has an anti-corrosive impressed current cathodic protection. This was a groundbreaking solution in Portugal.
- Coordination and detailed design. Dynamic seismic analysis. Hydrological and drainage studies. Geotechnical report and technical assistance during the construction phase.
