Workers from the Novo Porto Consortium, a group funded by a mix of public and private agencies, look on as debris is lifted out of the Binario tunnel, in Rio de Janeiro, Brazil. The tunnel is part of the $4-billion Porto Maravilha infrastructure project, which aims to revitalise the city’s downtown ahead of the 2014 soccer World Cup and the 2016 Olympic Games. The Brazil government has embarked on an urban infrastructure plan to prepare for the two events. To cope with the large volume of expected visitors, the preparation is heavily transport focused.
