New Stay Cable Bridge in the Metropolitan Area of São Paulo Improves Local Infrastructure

The city of Guarulhos borders São Paulo to the northeast. With approximately 1.3 Million inhabitants, it is part of the metropolitan area of São Paulo. It is also the location of São Paulo International Airport, the largest airport in Latin America.

Many of the country’s main highways run through Guarulhos. The Dutra Interstate, one of Brazil’s main highways, linking São Paulo and Rio de Janeiro, is a principal component of the highway network passing through Guarulhos. Since the existing feeder roads for Dutra Interstate were no longer able to cope with the high traffic load in Guarulhos, the city decided to improve the traffic flow by building a new feeder road.

The new highway exit will connect Paulo Faccini Road with Presidente Dutra Highway via a bridge, thus providing relief for city traffic. The new bridge is 170m long, with a main span of 96m. The bridge is designed as a stay cable bridge and is erected using the free cantilever method. The structure’s only pylon has a height of 61m. The road surface is 24m wide and will accommodate two traffic lanes into each direction as well as two footpaths and bike lanes.

The General Contractor Construções e Comércio Camargo Corrêa S.A. awarded Protendidos DYWIDAG a contract to supply of all of the DYWIDAG THREADBAR ^® Systems necessary for the stabilization of the bridge. Part of the Post-Tensioning Systems is used for stabilizing the foundation of a tower crane that is used during pylon construction. Additional DYWIDAG bar tendons are needed for temporarily post-tensioning the moveable cantilever formwork.

A total of 400m of 32mm diameter DYWIDAG THREADBAR ^® will be supplied by Protendidos DYWIDAG from their local factory in Guarulhos.

Protendidos DYWIDAG is proud to have been chosen as a specialist supplier of Post-Tensioning Systems for this project.
