The Buffalo Bills have broken ground on their new $1.54 billion stadium.

The agreements for the new home include a 30-year lease and a non-relocation agreement that makes it difficult for the team to leave Buffalo.

"While Buffalo isn't one of the larger NFL markets, the days of us operating as a small-market team are in the past," EVP/chief operating officer Ron Raccuia said.

"On the field, we've become a national brand, gaining national attention and attracting national opportunities. Our fans stretch across the country and the world, and as an organization, we carry this banner with commitment and pride."

The new stadium will officially also be called Highmark Stadium, as announced by Terry Pegula, thanks to a new naming rights agreement with Highmark Blue Cross Blue Shield of Western New York to extend the partnership with the Bills.
