9th of July Avenue is the main street in downtown Buenos Aires, Argentina. This name is given in honor of Argentine Independence Day, which is celebrated on July 9, 1816.
This avenue runs approximately 3 kilometers west of the Rio de la Plata promenade, starting at the Retiro area in the north and ending at Constitución station in the south. Stretching up to seven lanes in each direction, the avenue is surrounded by parallel streets, both of which have two lanes.
One of the city’s metrobus corridors runs through the middle of the avenue – a 3-kilometer bus rapid transit system that was launched in July 2013. Two wide middle lanes run between the side streets and the main road. It is currently the widest avenue in the world.
The northern end of the avenue is connected to the Arturo Ilha Expressway (which links to Jorge Newbery Airport and the Pan American Highway) and Libertador Avenue.
The southern end is connected to the May 25 Toll Highway (which serves the western part of Greater Buenos Aires as well as Ezeiza Airport) and the July 9 Elevated Expressway providing access to two major roads heading south out of the city ( route 1 to La Plata and route 2 to Mar del Plata).
Republic Square is located at the intersection of this avenue with Corrientes Avenue, and at this point is also the Obelisk of Buenos Aires.
