OEC begins work to complete northern stretch of Mario Covas Ring Road

Contracted by Via Appia Concessões, the Cantareira Consortium, led by OEC – Engenharia e Construção, will complete the implementation of the northern stretch of the Governador Mario Covas Ring Road, in the São Paulo Metropolitan Region. The work will make it possible to close the ring road, helping to improve traffic around the country’s largest city.

Work began on April 25 at the junction of the Presidente Dutra Highway (BR-116) and will cross the municipalities of Arujá and Guarulhos, passing to the south of the Serra da Cantareira State Park, until the intersection with the Tancredo Neves Highway, on the segment named Av. Raimundo Pereira Magalhães (SP-332), connecting the western and eastern sections, closing the entire ring road with the joining of the Fernão Dias (BR-381) and Presidente Dutra (BR-116) highways.

The construction work will employ around 5,000 direct employees at the peak of the project and its final delivery is planned for September 2026.

Flow and structure

The expectation is that more than 44,000 vehicles will travel along the stretch every day in each direction, avoiding heavy truck traffic on urban roads and contributing to better traffic flow throughout the region. The services will cover a total length of 44 km. The scope of the project includes 18 km of four-lane highway, 26 km of three-lane highway, seven double tunnels, 107 Special Works of Art, including bridges and viaducts, four stops for special loads, four bays for dangerous goods, two bases for the User Assistance Service, two general inspection posts and two weighbridges. The work will include civil works and tunnel systems, earthworks, containment works, drainage, paving, signaling, among other services.

The concessionaire is in the process of surveying all the pathologies, damage caused by the weather, evaluating the rework and updating the executive projects, since the works, before being taken over by Via Appia Concessões, had been paralyzed since 2018.
