The worlds widest boulevard has 16 lanes and took half a century to complete.

Avenida 9 de Julio in Buenos Aires, Argentina still holds the title of "World's Widest Avenue" with a width of about 140m and 16 lanes.

The world's widest boulevard has 16 lanes and took half a century to complete.

The history of this avenue began in the early 20th century, when the government of the Argentine capital decided to build a grand central street inspired by the Champs Elysees in Paris (France).

The Avenida 9 de Julio project was huge, going through many phases of construction, so it took nearly half a century to complete. Phase 1 was completed in 1937, and phase 2 in 1960. After 1980, the southern areas continued to be completed. Thousands of households and many houses were demolished to build this avenue. Since its completion, Avenida 9 de Julio has remained the widest avenue in the world.

Along this avenue are neatly planned buildings. To the south of the avenue is the Constitución train station, to the north is the French Embassy with its European-style architecture, the Teatro Colón theater. In the middle of the avenue is the 70m high Obelisco, inaugurated in 1936.

The world's widest boulevard has 16 lanes and took half a century to complete.

A TikToker attempted to cross Avenida 9 de Julio in Buenos Aires from one side to the other, and the total time, including waiting at red lights at intersections, was 4 minutes and 17 seconds. Meanwhile, the average crossing time on other avenues around the world is around 25 seconds.
