Buenos Aires Has the Widest and the Longest Street in the World The grand Avenida 9 de Julio is named after the country’s Day of Independence, celebrated on the 9th of July. This colossal avenue spans a staggering 459 ft in width and accommodates 16 lanes of traffic. The street is home to historic buildings, monuments, and landmarks like the Obelisco, making it worth exploring when you visit Argentina. While Av. Rivadavia has more than 35km of distance.

So, we Argentineans, have the widest and the longest! (if you know what I mean).
