The patriots stadium construction was owner funded.

"After the Hartford proposal fell through, Robert Kraft paid for 100% of the construction costs, a rare instance of an NFL owner privately financing the construction of a stadium."

Concurrently announced was a new road to access the stadium from U.S. Route 1 so not quite.

That doesn't mean the city paid for it. If you start a new land development to put up houses, you often cover all the costs associated with putting in roads and signs. Not saying that's what happened here but one sentence saying a road was put up doesn't indicate paid for by taxes.
