Porteños often boast about Avenida 9 De Julio as the world’s widest boulevard, and with a width of 460 feet (140 meters) with 12 lanes of traffic, they might just be right. Construction on the avenue began in 1937, modeled after the Champs Elysees but twice as wide, and built to commemorate Argentina’s Independence Day, July 9, 1816. It wasn’t fully completed until 1980.
Neo-classical and Beaux Arts buildings line the monumental street, but it’s most recognizable feature is the iconic Obelisco that towers over a small park at the intersection of Avenida 9 De Julio and Avenida Corrientes.
Don’t try to rush across the avenue. On average, a pedestrian needs two to three green lights to make it all the way across.
