Mota-Engil signs concession contract for submerged tunnel in Brazil and increases its order book in the country to €2.2 billion

Mota-Engil has already signed the concession contract for the construction of the immersed tunnel in Brazil, which will connect the cities of Santos and Guarujá, in São Paulo, and whose concession it won in September last year. With this project, the Portuguese construction group adds another €1.2 billion to its order book, bringing the value of its portfolio in Brazil to €2.2 billion.

“Mota-Engil announces that, through its subsidiary Mota-Engil Latam Portugal, it has signed the concession contract for the Public-Private Partnership (PPP) project for the construction, operation and maintenance of the Santos-Guarajá submerged tunnel, in the State of São Paulo, Brazil, with an investment amounting to approximately R$7.8 billion, equivalent to €1.2 billion”, the Portuguese company said in a statement sent on Thursday to the Portuguese Securities Market Commission (CMVM).

“The five-year construction contract will add approximately €1.2 billion to Mota-Engil’s order book and includes the construction of a tunnel with three lanes in each direction, with a light rail line, an area dedicated to cycle paths and pedestrians, as well as a traffic lane that will reduce the crossing time from around one hour to five minutes”, explains the company.

All told, the construction company led by Carlos Mota dos Santos has increased the value of its current order book in the South American country to around €2.2 billion, a market where the company identifies “high potential for deepening its presence and investment in the medium and long term”.

In September 2025, Mota-Engil won the auction for the concession of Brazil’s first submerged tunnel, for a period of 30 years. The contract includes “the construction of the first submerged tunnel in Brazil, with a total length of around 1.5 kilometres, of which 870 metres are submerged under the access channel to the port of Santos, with the concessionaire receiving, after the start of operation, a fixed annual revenue equivalent to R$436.1 million”, the statement said.

The contract also provides for additional revenue estimated at around R$2.5 billion during the operating period (25 years).
