The Government of São Paulo, through the Secretariat for Investment Partnerships, has begun mobilization work for the widening and improvement of the Washington Luís Highway (SP-310), in the São José do Rio Preto region. The work will begin in April and will cover the municipalities of Cedral, São José do Rio Preto and Mirassol.
With an estimated investment of R$455 million, the project will be carried out by the Ecovias Noroeste Paulista concessionaire, under the supervision of the São Paulo State Transportation Agency (ARTESP). The works are expected to be completed in the second half of 2027.
“This is another of the major investments planned in road concessions in the state of São Paulo. The works will improve fluidity in the region, solving an existing bottleneck, as well as boosting regional development,” said Rafael Benini, the state’s Secretary for Investment Partnerships.
The work includes the construction of 15.8 kilometers of bypasses between km 436 and km 446, in São José do Rio Preto; at km 425, in Cedral; and near km 448, in Mirassol. A further 26.3 kilometers of third lane will be built between km 428 and km 436 and between km 444 and km 452. Most of the new lanes will be built on the central median.
Another highlight of the project is the complete overhaul of the interchange with the Transbrasiliana Highway (BR-153), with the implementation of new access loops and return viaducts. Improvements will also be made to the accesses to São José do Rio Preto.
A total of 11 viaducts will be built along the stretch between Cedral and Mirassol, with structures designed to handle both the main traffic and that on the side roads.
As well as increasing the highway’s capacity, the works will improve traffic flow and increase road safety, with the separation of long-distance vehicles from urban traffic. The project is also expected to generate direct and indirect jobs and contribute to regional economic development.
During execution, the concessionaire will adopt traffic signaling and management measures to maintain flow on the unaffected lanes. The population will be informed in advance of any closures via the local press, the company’s digital channels and signs on the highway itself.
