Cable-stayed bridge at Santa Apolonia

1998 can be defined for Portugal the year of the infrastructures.
1998 can be defined for Portugal the year of the infrastructures. The realisation of the World Expo in Lisbon has given the Lusitan Country the opportunity of reinforcing the Highway connection between Porto and the North of Spain and Lisbon and the South of Portugal, and the occasion to develop the Roadway system around the City (among the varioys projects noteworthy the famous Vasco da Gama bridge, the reinforcement of the interchanges connecting Lisbon to the airport area, and the ways linking the city to the exposition area).
The bridge (Viaduto Rodoviario Sobre o Feixe de Linhas de Sta. Apolonia - prolongamento da Av. Mouzinho de Albuquerque), connects the road alongside the Tagus bridge with the center of Lisbon, crossing the existing Railways of the Santa Apolonia station.
The main is a radical cable-stayed design, with a single pylon. The stays are made of hot dip galvanised, 7 wires, 15.2 mm. diameter, high strength (1860 N/mm2), HDPE coated strands and externally protected by white HDPE sheaths.
One plane of 8 cables, from 31 to 46 strands each, supports the deck with a clear span of 90 metres; they are balanced with 8 back stays from 19 to 55 strands each. A total of 42 tons of strand has been used for the stays: the longest cable is 77 metres. Stay cables are protected at the deck end by galvanised steel anti-vandalism tubes.
The extremity anchorages are fixed at the bottom end (into the box girder) and adjustable at the upper end (into the pylon), to allow the stays load regulation anythime.
The stay cables have been installed by a Tensacciai team, utilising a particular very compact and quick threading equipment. The strands have been tensioned by isoelongation with reference to a witness strand of pre-fixed lengths.
