Santos and Guarujá, São Paulo, Brazil | Santos Guarujá Tunnel
As the largest port in Latin America, the Port of Santos, Brazil, processes approximately 7 million tons of cargo per month and hosts the
largest fleet of cruise ships in Brazil. The channel entrance separates the popular beachfront cities of Santos and Guarujá. To improve
mobility and reduce the average travel time between the cities, a new 870-meter tunnel with 950 meters of access ramps will run 21
meters beneath the channel.
Engevix Engenharia, Themag Engenharia, and Planservi Engenharia partnered to engineer the BRL 2 billion project. In a technological
first for Brazil, all parts of the tunnel will be built on the surface, and then submerged to the channel bottom. Bentley Power Civil for
Brazil rapidly developed the geometry and visualized the project. Project Wise enabled collaboration of international teams while
maintaining data security. Both products reduced lead time by facilitating interaction among disciplines.
A major challenge was adjusting the geometry of roadways to access the tunnel from densely built, historic areas of the cities. The
alignments will avoid interference with protected mangroves, and historical and cultural assets. During peak season, the tunnel will
enable 35,000 cars per day to cross the channel, reducing the average crossing time from 90 minutes to just two minutes.
