Infante D. Henrique Bridge

Oporto, Portugal


ACE Edifer/Necso



Detalhes

afassociados formed part of a consortium with Portuguese contractors Edifer, Spanish engineers IDEAM and Spanish contractors Necso. The construction started in 1999 and completed in 2002. The bridge is now open to traffic.

The engineering design team, decided to take advantage of the presence of solid rock in the foundation areas. The winning design is of the type known as a “deck-stiffened arch”. This form, pioneered in the 1920s and 30s by the Swiss engineer Robert Maillart, considers that the supporting arch structure acts in conjunction with the deck structure.

Whereas Maillarts bridges had spans in the range of 30 to 40 metres the Ponte Infante Dom Henrique spans 280m with an arch rise of 25m.

The deck is a box structure of prestressed concrete whereas the arch and vertical elements are of reinforced concrete.
