The Nicolás Avellaneda Bridge also connects the Isla Maciel (in Dock Sud) with La Boca neighbourhood.

The Partido was known as Barracas al Sud (Southern Barracks), until it was renamed in honor of Nicolás Avellaneda in 1904.

The Avellaneda Partido is subdivided into four cities and four localities (localidades), listed here with their populations (as of 2001): Between Dock Sud, Sarandí, Villa Domínico and Wilde there is an area called Reserva Cinturón Ecológico, ("Environmental Belt Rerserve Area") which is a part of a network of waste dumps, which after reaching capacity are planted with greenery.

Avellaneda is home to two of the most famous football clubs in Argentina: Independiente and Racing.

The partido is also home to several other football teams including Arsenal de Sarandí of the Primera Division Argentina, and lower league teams San Telmo, Dock Sud and Victoriano Arenas.
