The company’s experience is also being used to expand the capacity of important federal highways, as is the case of the final engineering project for the side roads of BR-116 – Via Dutra (Arujá-São Paulo section), over a 32 km extension.

In the following decades, Sondotécnica would also complement the final engineering project of the Dutra side roads (Cumbica-Guarulhos section), restore the Guarulhos-São Paulo subsection and supervise the execution of the planned services and control of the works on the highway.
