This infrastructure aims to significantly reduce travel time from an hour to five minutes for approximately 720,000 users of the existing routes.

The project is anticipated to enhance the competitiveness of the Port of Santos, the largest port in Latin America, and stimulate economic activity while promoting sustainability by lowering fuel consumption and emissions in the region.

This contract represents a significant milestone under the New PAC – Growth Acceleration Plan, increasing Mota-Engil’s backlog in Brazil to around €2.2bn.

The Mota-Engil Group sees considerable potential for further investment and expansion in the Brazilian market in the medium to long term.
