General description
Timbúes, San Martín and San Lorenzo, together with other smaller towns, constitute the northern area of Greater Rosario, in the province of Santa Fe. With about 60.000 inhabitants, this area has important industrial plants, especially agro-industrial, chemical, petrochemical and oil. The Nuevo Central Argentino and Belgrano railway lines provide good connections in every direction except east. The port area is connected by an excellent road network and the new bridge between Rosario and Victoria now connects it to the Mesopotamia region. The Rosario and Rosario-Santa Fe highways by-pass the urban areas and allow a swift approach without mixing with local traffic. The Rosario international airport is 32 km away.
