When you say construction, do you mean renovations? The current stadium dates back to 1973. Atlanta has gone through the Georgia Dome and now another newer dome since then.For the record, A, the City of Buffalo has nothing to do with Bills stadium negotiation. That would change if the Bills were considering a downtown site. But from what we know, the Pegulas are proposing the new stadium for suburban Orchard Park, adjacent to the existing one. The primary level of government during the past two stadium lease negotiations (in 1998 and 2012) was New York State. That appears to be the case this time. Erie County government does play a role as the official owner of the stadium. County Executive Mark Poloncarz wrote a book about the last stadium negotiation, which I should read to be able to address this issue. Still, I don’t recall there ever being a public vote in past negotiations. The state and team came to an agreement. The Erie County Legislature gave its approval, and construction began.
It appears the current lease expires in 2023.
Buffalo will need to expedite building a new stadium. Roger Goodell made it pretty clear that the Bills won't be staying in Buffalo without a new facility. A dome would be logical so it could used for other events...
