AVELLANEDA, a city in the Argentine republic, pop. 46,277 in 1914, and estimated to be about 160,000 in a suburb of Buenos Aires, on the southern side of the Riachuelo which separates it from Buenos Aires proper. It is virtually a part of the capital but is organized as a separate municipality. Avellaneda is one of the new cities of the Argentine, owing its rapid development to the growth of Buenos Aires in recent years. It is chiefly industrial and commercial in character, and contains meat-packing plants, wool-washing establishments, textile mills and extensive markets for agricultural and stock products. Two railways (the Great Southern and the Midland) have been built into Avellaneda from Buenos Aires, and it is also reached by tramways and motor-bus lines. Several bridges span the Riachuelo, connecting Buenos Aires and Avellaneda.
