Web Desk: Do you know which is considered the widest road in the world, where it is located, and when it was built? And what was the purpose behind its construction?

Most people may not be familiar with this fascinating fact, so let’s take a closer look at this remarkable roadway.

According to Guinness World Records, the world’s widest road is Avenida 9 de Julio, located in the capital city of Argentina, Buenos Aires. It is not only known for its extraordinary width but also for its historical and architectural significance.

Historical Background

Avenida 9 de Julio carries great historical importance and reflects the colonial-era transformation of South America. In the early 20th century, Buenos Aires was often referred to as the “Paris of South America.” To strengthen this image, the local government initiated several major urban development projects.

One of these ambitious projects was Avenida 9 de Julio, designed to resemble the famous Champs-Élysées in Paris. However, city planners went even further, aiming to create an avenue so wide and impressive that it would symbolize Buenos Aires as a modern global city.

Construction of the road began in 1937 and was completed in multiple phases over several decades. In total, it took nearly 50 years to finish the project.

Due to its massive scale and central location, the project faced numerous challenges, including the relocation of several buildings and complex traffic and infrastructure adjustments.

The construction was finally completed in the 1980s. The avenue spans approximately 140 meters in width and consists of 16 traffic lanes, making it officially recognized by Guinness World Records as the widest road in the world.

Avenida 9 de Julio remains one of the most iconic landmarks of Buenos Aires, reflecting both its historical ambition and modern urban identity.
