Ponte do Galeão

The Ponte do Galeão is located in Rio de Janeiro in the Guanabara Bay and connects the Ilha do Governador ( Portuguese Governor 's Island) with the Ilha do Fundão (Fundão Island), which lies close to the mainland and is connected to it by numerous bridges.

It was the first and is now one of the four bridges that lead from the south to Rio de Janeiro-Antônio Carlos Jobim Airport , officially Aeroporto Internacional do Galeão no Rio de Janeiro .

Before it opened in January 1949, the Base Aérea do Galeão air base on Praia do Galeão ( Galleon Beach ) on the Governor's Island, next to which the Aeroporto do Galeão was developing, could only be reached by launch .

It was the first prestressed concrete bridge in Brazil .

description

The former six-lane bridge, now only four lanes, leads the Av. Brg. Trompowski to the airport.

The T- beam bridge is 368.4 m long and 20.6 m wide. It has 15 openings with pillar spacing (from north to south) of 4 × 19.4 + 28.3 + 37.2 + 43.4 + 37.2 + 28.3 + 6 × 19.4 m. Each bridge field consists of 19 parallel prestressed concrete double T-girders, which were prefabricated in coordination with the STUP - Société Technique pour l'Utilisation de la Précontrainte outside the construction site using the Freyssinet system using the pre-tensioned bed method . They were covered with a concrete slab and protected from the omnipresent moisture with a layer of asphalt.

The substructure consists of yokes with 3 piles each.

The bridge apparently survived the course of time without major damage.
