One of the distinctive structures in Buenos Aires is the widest highway in the world, Avenida 9 de julio that runs through the middle of the city, up to seven lanes each way.

Unfortunately for us, we rode up and down this landmark both directions while searching for the exit to the neighborhood of our rental apartment. We discovered that highways may have up to three different names AND a number and that all or none of these may appear on road signs. We drove past our exit various times, finally getting off after about six tolls that we didn’t want, but had to pay in order to turn around and head back toward the city.
We found it, and the good news is that our apartment is lovely, on Colombres in the Boedo neighborhood.
