‘Rodovia dos Imigrantes’ – (official designation SP‑160) is a highway in the state of São Paulo, Brazil. The highway connects the city of São Paulo to the Atlantic coast and with the seaside cities of São Vicente and Praia Grande. It follows the route of Rodovia Anchieta and is also one of Brazil’s busiest highways, especially on weekends.
Rodovia dos Imigrantes has 44 viaducts, 7 bridges, and 11 tunnels, along its 58.5 km stretch. The highway has recently been expanded, in one of the most audacious feats of Brazilian highway engineering, with extremely long tunnels and high strutting six-lane bridges constructed over the tropical rain forest which covers the steep faces of the Serra do Mar, the cliff range that separates the São Paulo plateau from the seaside lowlands. During sunny weekends, more than 1 million automobiles commonly cross its near 60 km run, separating the city of São Paulo from the sea. (Text: Wikipedia)
