A highway in the state of São Paulo, Brazil, that 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. It 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-lana bridges constructed over the tropical atlantic forest, which covers the steep faces of the Serra do Mar, the cliff range that separates the São Paulo plateau from the seaside lowlands.
Rodovia dos Imigrantes was inaugurated in 1974, due to traffic saturation on Rodovia Anchieta. Although longer than Anchieta, Rodovia dos Imigrantes is nowadays busier due to its building standards, which permit higher speeds limits, and its more direct path to the cities of Santos and Guarujá, the northern coast (with Bertioga), as well as the southern coast (with Mongaguá and itanhaém)
