The Minnesota Vikings are adding $647,000 to their share of their new stadium thanks to several design changes.

The changes are up for approval at Friday's meeting of the authority overseeing the stadium's construction.

The biggest share is almost $235,000 to change finishes and food service capabilities in one section of the stadium. There's an additional $116,000 to redesign the Vikings' locker room, plus $146,000 to redesign end zone seating.

The stadium's price tag is around $1 billion, with taxpayers covering $477 million. It's due to open in 2016.
