The projected cost of the Buffalo Bills’ new stadium has ballooned to what team officials on Friday told The Associated Press is “north of $2.1 billion,” with owners Terry and Kim Pegula responsible for picking up the more than $560 million in overruns.

Bills president Pete Guelli said he was not surprised by the amount, given how the numbers have been tracking up since construction began 16 months ago. And he said the projected total represents the commitment the Pegulas have to the community because they are sticking to their vision for the facility without cutting corners to reduce costs.

“To sum that up, the Pegulas will not deviate from building a best-in-class stadium in Buffalo,” Guelli said.

Taxpayers are committing a combined $850 million to the project — $600 million from the state and $250 million from the county. At the time of the deal reached two years ago, that represented more than half the cost of construction, but now, taxpayers will be responsible for about 40%. The Bills are responsible for any overruns beyond $1.54 billion.
