Buenos Aires is fast becoming one of the most admired cities in the world when it comes to reinventing streets and transportation.

Just over a year ago, the city launched MetroBus BRT (constructed in less than seven months) on 9 de Julio Avenue, which may be the world's widest street. The transformation of four general traffic lanes to exclusive bus lanes has yielded huge dividends for the city and is a bold statement from Mayor Mauricio Macri about how Buenos Aires thinks about its streets. More than 650,000 people now ride MetroBus every day, and it has cut commutes in the city center from 50-55 minutes to an incredible 18 minutes.

That's not the only benefit of this ambitious project. The creation of MetroBus freed up miles of narrow streets that used to be crammed with buses. Previously, Buenos Aires had some pedestrian streets, but moving the buses to the BRT corridor allowed the administration to create a large network of shared streets in downtown where pedestrians rule. On the shared streets, drivers aren't permitted to park and the speed limit is an astonishingly low 10 km/h. Yes, that is not a misprint -- you're not allowed to drive faster than 6 mph!

Bicycling has also increased rapidly in the past four years -- up from 0.5 percent mode share to 3 percent mode share and climbing. Ecobici is the city's bike-share system which is expanding to 200 stations in early 2015. Oh, and add this amazing fact: Ecobici is free for all users for the first hour.
