The widest: 9 de Julio Avenue

Next time you're on that busy perimeter highway around a major American metropolitan area, slow down and thank your lucky stars that you're not stuck in traffic on 9 de Julio Avenue in Buenos Aires, Argentina.

Named after the country's independence day — July 9, in 1816 — it boasts as many as nine lanes in each direction and spans the width of a city block.
