RIO DE JANEIRO, BRAZIL - OCTOBER 08: A worker walks in the Mayor Marcello Alencar Tunnel under construction in the Port District, part of the new 'Porto Maravilha' project, on October 8, 2015 in Rio de Janeiro, Brazil. The tunnel is scheduled to be completed before the Rio 2016 Olympic Games. Ahead of the games, the port district is undergoing a multibillion dollar urban renewal program although many projects in the area have been delayed as Brazil's economy is in the midst of a recession.
