Key Data


Mario Covas Beltway, São Paulo

Mario Covas Rodoanel Beltway (SP-21), also known as the São Paulo metropolitan ring road, is a 177km road currently being built around the city of Sao Paulo in Brazil. It has been named after Mário Covas, a former mayor of the city of Sao Paulo.

The ring road connects ten major highways leading into Sao Paulo. The road is expected to be ready before the FIFA World Cup in 2014.

The project is being managed by Desenvolvimento Rodoviario (Dersa), a state highways company that is responsible for awarding and monitoring all private sector concessions.

The road, upon completion, will reduce truck traffic in Sao Paulo by 40%.

Details of the major Brazilian road project

"The road is expected to be ready before the FIFA World Cup in 2014."

The first step towards the project was taken in 1952. Before 1992, Dersa considered three alternatives and many variations of the Mario Covas ring road. Finally, in 1998, Dersa got the approval for project construction.

The main objective of the project is to improve the quality of life in the Greater Sao Paulo area by eliminating heavy traffic loads and connecting all roads to Santos port.

It is also aimed at mitigating accidents involving dangerous materials, as well as controlling and preventing pollution.

More than 1.1 million vehicles drive into Sao Paulo daily, leading to the damage of roads, congestion, traffic jams and pollution. Once completed by 2014, the ring road project will reduce traffic congestion in central Sao Paulo by avoiding more than 300,000 vehicles entering into the city.

Construction of the Mario Covas Beltway

The road execution was divided into four sections - west, south, east and north sections. The west and south sections were delivered in October 2002 and April 2010 respectively.

Construction is currently underway in the east and north sections, which is expected to be completed by 2014.

The western section is a 32km-long road, which was delivered in October 2002.
