ST. PAUL  (AP) - A written agreement between the Minnesota Vikings and Ramsey County that lays out terms of their football stadium deal in Arden Hills says the facility would be publicly owned and leased by the Vikings, and would have a retractable roof unless the team decides it's too expensive.

If the team decides the retractable roof costs too much, the team could decide to build a fixed roof instead. It says the team would be responsible for some but not all cost overruns.

The agreement says the team and county agree that transportation improvements needed at the former Army ammunitions plant site are the responsibility of the state of Minnesota. State lawmakers pushing the stadium at the Capitol say that's a problem if the state share goes higher than $300 million.
