At 416 feet (127m) wide, spanning the width of an entire city block, Avenida 9 de Julio is claimed to be the widest avenue in the world. Named for Argentina's Independence Day which falls on 9 July, the avenue was only completed in the 1960s, some 70 years after its original planning. The avenue runs from the Retiro district in the north to Constitucion station in the south, roughly one kilometre to the west of the Rio de la Plata waterfront, and consists of 18 lanes of traffic, nine on each side. In the middle of the street stands the impressive 67-metre-tall obelisk marking the heart of Buenos Aires.
