Avenue 9 de Julio, known as the “widest avenue in the world” with more than 20 lanes of car traffic, has undergone an impressive “transit makeover” in the last year. The city replaced car lanes with bus-only lanes and created a high-quality, median-aligned bus corridor with 17 stations, accommodating 11 bus lines and improving travel for 200,000 passengers per day. Although the project was often politically difficult, the results are speaking for themselves: across the board, passengers have reduced their travel time by an average of 30 minutes per bus ride. It used to take more than 40 minutes to cross the city. Now it takes an average of 14.

The 9 de Julio Avenue corridor project is part of a citywide Sustainable Mobility Plan initiated in 2009. The plan includes the pedestrianization of more than 100 blocks of the Microcentro area, an extension of the public bicycle share system, a 300 km bicycle-lane network, interventions prioritizing pedestrian activity and public transport, traffic calming and road safety infrastructure, and a sweeping on-street parking-reform project planned for 2014 that will incorporate best practices from around the world to combat illegal parking and improve traffic flow.

In addition to the 9 de Julio corridor, Buenos Aires opened the Metrobus Sur BRT corridor in September 2013. Metrobus Sur runs in two branches, General Roca and Fernandez de la Cruz, with an interchange Puente La Noria with Constitution transport hub. The BRT has 32 stations, and carries 250,000 passengers per day.
