The Olympic Games in the “Cidade Maravilhosa” may have come to an end, but even after the effervescence of such an event, it is now obvious that Rio has risen as a vibrant global metropolis. It is time for Tunnelling Industry to review and highlight projects that were part of the Olympics success. If this worldwide competition was a particular moment for athletes to shine, it was also a momentous occasion for the Tunnelling Industry to introduce major projects undertaken in the city. Indeed, as the organizer of these Olympic Games like previous cities: London, Sochi or Beijing, Rio had to prepare and make some improvements; numerous projects were launched in order to facilitate mobility and access to the different venues.
