BR-285 is an east-west Brazilian federal highway that starts in Araranguá, Santa Catarina, and crosses the Gaucho range and highlands.

[2] During the summer months, BR-285 receives a large flow of vehicles from Argentina, heading for the beaches of Rio Grande do Sul and Santa Catarina.

From there, drivers who decide to spend the summer on the riograndense beaches descend to Caxias do Sul to take the Rota do Sol to Terra de Areia.

There is an unpaved section between the cities of São José dos Ausentes and Timbé do Sul, so the movement of vehicles is very low.

In August 2020, only 8 km remained to complete the paving of BR-285, between the city of São José dos Ausentes and the border with Santa Catarina.
