Construction problems in Brazil for the upcoming Confederations Cup continue to plague the country. Among the structures not yet completed is the iconic Maracana Stadium.

More than half a million tickets have been sold for the Confederations Cup in June, but host nation Brazil has yet to finish the main stadiums to be used in the dress rehearsal for the next year's World Cup.

World soccer's governing body FIFA demanded all six stadiums be ready by this past December but construction delays forced it to extend the deadline until April 15. Even with that extra time, all the stadiums will not be ready. The pitch has been laid and more than half the 7,800 seats have been installed, but work is still being done on the massive roof while work to the access areas to the stadium has not started.

Maracana was supposed to be ready this past December but that date was repeatedly pushed back. The earliest it will be handed over to FIFA is April 27, but FIFA and Rio state officials doubt the stadium will be finished even then.
