See what changes in traffic with the release of the Sebastião Gualberto tunnel and viaduct, in São José dos Campos

The tunnel and viaduct on Avenida Sebastião Gualberto, in São José dos Campos, are scheduled to be released this Friday (30). Two temporary traffic lights will be deactivated.

Drivers should be aware of occasional closures for repairs over the weekend. A road over the tunnel still remains to be completed to connect the regions.

The delivery deadline for the duplication was postponed from 2026 to January 2027. The cost of the work rose to R$104 million.

The tunnel that connects Avenida Senador Teotônio Vilela to Avenida Sebastião Gualberto and the viaduct that connects Avenida João Marson to Avenida Teotônio Vilela, in São José dos Campos, are scheduled to be released from 4pm this Friday (30).

The structures are part of the duplication works on Avenida Sebastião Gualberto. According to Vladimir Melo Júnior, director of Road Improvements at the Urban Mobility Secretariat, the release will be carried out with the support of mobility agents. With the opening, two traffic lights that work temporarily in the region will be deactivated.

Despite the release, drivers should be aware of occasional closures during the weekend, necessary to carry out repairs on the pavement.

In the early hours of Friday to Saturday (31), it will be necessary to close the beginning of Avenida Teotônio Vilela, close to the viaduct, towards the south zone. During the service, drivers coming from the north must pass through the central region of the city, along Avenida 23 de Maio.

Heavy vehicles will have a specific detour through the underpass, with guidance from mobility agents, until the first return. On Saturday (31st) and Sunday (1st), repairs will be carried out on Avenida João Marson, in the section used by those traveling from the east to the north.

During the interventions, drivers must access the viaduct, turn around on Avenida Teotônio Vilela and use the tunnel towards the north. According to City Hall, after the repairs are completed, the tunnel and viaduct will operate normally.

Despite the release of the two structures, one stage of the work still needs to be completed: the construction of a road over the tunnel, which will allow direct connection between the north and east regions of the city. Currently, drivers taking this route need to use a U-turn in the region.

According to Vladimir Melo Júnior, the completion of the embankment and the new road will allow the work on this stretch to be completed and facilitate circulation between the two regions.

The delivery of the duplication works on Avenida Sebastião Gualberto was initially scheduled for the first half of 2026. In June of this year, however, City Hall postponed the deadline to January 2027.

According to Vladimir Melo Júnior, the schedule was impacted by difficulties related to the release of areas necessary to carry out the work.

Among the obstacles are Union land that depended on authorization, areas under MRS concession and expropriations that needed to meet court deadlines.

The director also pointed out geotechnical difficulties, especially in the region close to the river, where soil conditions required additional care in the execution of foundations and embankments.

The cost of duplication works has also increased. The value now stands at R$104 million, an increase of R$22 million compared to the previous budget.
