Located in Buenos Aires, Avenida 9 de Julio is an urban landmark and symbol of the grandiosity of the Argentine capital. See more details of the widest avenue in the world
Avenida 9 de Julio, located in Buenos Aires, Argentina, is officially the widest avenue in the world. With about 140 meters in width and a total of 16 lanes, it continues to impress residents and tourists. Its name refers to the date of Argentine independence, celebrated on July 9.
The construction of the avenue began with grand ambitions. The Argentine capital, nicknamed “Paris of South America”, wanted to reinforce this title with a monumental roadway.
Inspiration came from the Champs-Élysées in Paris, but the intent was to surpass the French model with a wider and more imposing avenue.

One of the biggest mudslides ever recorded on the Trans-Amazon Highway trapped trucks, cars, and motorcycles at the same spot for three consecutive days while a tractor with a winch tried to free them one by one under the rain.
The work took almost 50 years to be completed. In 1980, it was officially finished and has held the world record since then.
Urban Challenges And Social Impact
Creating space for an avenue of this magnitude in the center of a major metropolis required drastic decisions.
About 60 thousand square meters of real estate were demolished. Additionally, thousands of residents had to be displaced. All of this to make way for the first stretch of the avenue.
The scale of the work didn’t stop there. The roadway has been expanding over time and now includes four lanes dedicated to public transport, seven sidewalks for pedestrians, and a central area. Crossing from one side to the other takes time and patience.
A Crossing That Tests The Clock
A recent video posted on TikTok shows a user crossing the entire width of Avenida 9 de Julio. Even walking faster than usual, it took him 4 minutes and 17 seconds to cross. The time includes waiting periods at traffic lights. In comparison, crossing a typical avenue takes an average of 25 seconds.
The title of the widest avenue in the world is secured by a technical detail. Avenida 9 de Julio incorporates Carlos Pellegrini Street to the east and Cerrito Street to the west.
Together, they add six additional lanes. Without this junction, the width of the avenue would drop to 120 meters, below the officially recorded 140 meters.
