BR-453, also called the Rota do Sol (Route of the Sun) is a federal highway in Brazil with a length of approximately that links the east coast of Rio Grande do Sul to the Serra Gaúcha (Gaucho mountain range). The highway starts in Venâncio Aires and ends in Terra de Areia, Rio Grande do Sul.
Work on the highway began in 1972 and was completed in 2008. BR-453 functions as a shortcut to the beaches of Rio Grande do Sul, shaving off from the old route. Before the construction of BR-453, all road traffic going from the Gaucho Range to the coast had to drive through the capital city of Porto Alegre and go along BR-290 (referred to as "Freeway" in Portuguese).
