Elevado da Perimetral, Former elevated road in Rio de Janeiro, Brazil

Elevado da Perimetral was a supplementary elevated roadway built over Avenida Rodrigues Alves, linking the Santos Dumont Airport area to the Rio-Niterói Bridge, the Red Line and Avenida Brasil. It crossed Caju, part of São Cristóvão, Santo Cristo, Gamboa and Saúde, carrying an estimated 40,000 vehicles.

Construction began in the 1950s and proceeded in stages. The first section, linking Santos Dumont Airport to the Candelária church, opened in 1960; the second, over Avenida Rodrigues Alves around the port zone, was started in 1968 and opened in 1978. Demolition began in November 2013 and the last implosion took place in April 2014 under the Porto Maravilha project.

The structure created physical separation between neighborhoods and changed how people moved and connected across the city.

The elevated roadway no longer exists: the first section came down in November 2013 and the last implosion took place in April 2014. Its traffic was redirected into the Via Binário do Porto and the Binário and Via Expressa tunnels, so visitors now cross the port area at street level. Look for the former route above Avenida Rodrigues Alves.

During the 2013–2014 demolition, six steel beams valued at about 100,000 reais vanished from the port zone and were never recovered. Before demolition, some critics proposed keeping the structure as hanging gardens or a low-noise monorail linking Santos Dumont and Tom Jobim airports.
