Avenida 9 de Julio
As you may already know, Avenida 9 de Julio is the widest street in the world. However, on closer inspection I found this to be unfair: it really consists of three avenues. In this picture, my camera is facing south, so you can see the westernmost one. The other two are on your left. The Obelisk (in the background) marks the intersection with Corrientes - one of the main commerical streets of the city.
