The Polish organizing committee made the announcement on Monday _ 500 days before the start of the event that is to be co-hosted with neighboring Ukraine. The tickets will be available through UEFA's website.
The organizing committee insisted all preparations were on track. But Prime Minister Donald Tusk says that not all highways planned to link the tournament's host cities will be ready on time.
Tusk did not name those lagging behind, but insisted that about 81 key projects like stadiums, hotels and transportation links will be finished on time.
