Trans-Amazonian Highway

The Trans-Amazonian Highway (official designation BR-230, official name Rodovia Transamazônica), was inaugurated on August 30, 1972. It is 5,300 km long, making it the third longest highway in Brazil. It runs through the Brazilian states of Piaui, Maranhão, Tocantins, Pará and Amazonas, from the proximities of Saboeiro up until the town of Lábrea.
The highway was intended to integrate these regions with the rest of the country, and with Peru and Ecuador. It was originally planned to be a fully paved highway 5200 kilometers long. However, these plans were modified following its inauguration.
