The officials outlined the measures at a briefing on Wednesday at the stadium in East Rutherford, N.J.
Fans arriving at the game by mass transit on Feb. 2 will encounter a security perimeter extending 300 feet from entrances to the stadium. They'll be funneled into temporary pavilions for airport-style screening.
Behind the scenes, FBI and other agencies will closely monitor potential terror threats. Snow plows will be on standby in case of severe weather.
The officials said they studied past Super Bowls to prime themselves for possible problems like the power outage last year in New Orleans.
