When I first spotted this in Google Maps, I was struck by the similarity (at first glance anyway) to Chicago’s Circle interchange.
The north-south road portrayed above is the 9 de Julio Avenue, a broad multi-carriageway surface parkway in the urban center of Buenos Aires. The east-west freeway is the Autopista 25 de Mayo, which performs a similar function in an east-west orientation, but as a controlled-access facility and with less landscaping.
