Buenos Aires, Argentina, features the widest avenue in the world.
At over 300 feet wide, 9 de Julio Avenue occupies a gap of an entire block in the city grid, hence its incredible width.
Crossing the avenue at street level often requires a few minutes, as all intersections have traffic lights.
Under normal walking speed, it takes pedestrians normally two to three green lights to cross its twelve lanes of traffic.
