Rio Olympic Park construction progress (photos)
The Rio Olympics will start in a little more than 600 days. Until then, it will be interesting to see how venue construction progresses for the first Olympics in South America.
Organizers released pictures of the Barra Olympic Park and its cluster of venues this week. Barra will have the most venues of the four Olympic clusters in Brazil.
