Among the main Brazilian waterways, two stand out: Hidrovia Tietê-Paraná (which has a length of 2,400 km, 1,600 on the Paraná River and 800 km on the Tietê River, draining agricultural production from the states of Mato Grosso, Mato Grosso do Sul, Goiás and part of Rondônia, Tocantins and Minas General) and Hidrovia do Solimões-Amazonas (it has two sections: Solimões, which extends from Tabatinga to Manaus, with approximately 1600 km, and Amazonas, which extends from Manaus to Belém, with 1650 km. Almost entirely passenger transport from the Amazon plain is done by this waterway, in addition to practically all cargo transportation that is directed to the major regional centers of Belém and Manaus). In Brazil, this transport is still underutilized: the most important waterway stretches, from an economic point of view, are found in the Southeast and South of the country. Its full use still depends on the construction of locks, major dredging works and, mainly, of ports that allow intermodal integration. In Argentina, the waterway network is made up of the La Plata, Paraná, Paraguay and Uruguay rivers. The main river ports are Zárate and Campana. The port of Buenos Aires is historically the first in individual importance, but the area known as Up-River, which stretches along 67 km of the Santa Fé portion of the Paraná River, brings together 17 ports that concentrate 50% of the total exports of the country.
