Ventilation of the Marcello Alencar Tunnel - Expressway

FanTR is responsible for the ventilation system of the Marcello Alencar Tunnel, known as the Expressway Tunnel, which runs underground through the neighborhoods of Centro, Gamboa and Saúde, located in the Central Zone of the city of Rio de Janeiro. With 3,382 meters long, it connects the Rio-Niterói Bridge and Avenida Brasil with the Aterro do Flamengo - serving as an express corridor between downtown and the South Zone of the capital of Rio de Janeiro. It is also part of the Porto Maravilha Project, to revitalize Rio de Janeiro's port area.

It has two galleries: one towards Caju, in the port area, called Mar, and another towards the South Zone, called Continente. Each gallery has three tracks. The deepest point of the Via Expressa tunnel is 46 meters. For this project, FanTR supplied 44 fans, installed in pairs along the entire length.

The Marcello Alencar Tunnel replaced the Elevado da Perimetral and was once considered the largest underground tunnel in Brazil - a position currently held by tunnel of the Tamoios highway, which also has FanTR products.

Our fans can withstand temperatures of 400°C for up to two hours, in accordance with European fire protection standard EN1201-3. In the event of a fire, ventilation ensures clean air during evacuation.
