The Wilf family will contribute an additional $19.5 million toward upgrades to the Minnesota Vikings ongoing $1.06 billion stadium project.

The family contribution, according to owner Mark Wilf, will be nearly $551 million with the $498 million difference falling to the public, which voted in favor of the stadium to replace antiquated downtown Hubert H. Humphrey Metrodome. The Minnesota Twins had been co-tenants of the stadium until constructing their own outdoor venue downtown, Target Field.

Target Field has hosted the MLB All-Star game and the new Vikings’ stadium has been awarded a Super Bowl in 2018.

The Wilf family’s latest financial contribution goes toward enhancements in the plaza, food service equipment, entertainment areas in the stadium, upgrades to retractable seating and a deck overlooking downtown Minneapolis.
