Super Bowl

How the Super Bowl will manage security

Security at the first Super Bowl in the New Jersey/New York area will top that of any event since 9/11.

Safety measures are so intense that related equipment and personnel have claimed nearly two-thirds of the parking lot, according to Woody Johnson, owner of the New York Jets and co-chairman of the NJ/NY Super Bowl Host Committee.

Only 11,000 to 13,000 parking spaces are left, he told CNBC in an interview Friday. The venue, MetLife Stadium, has a capacity of 82,566.

Johnson, whose team plays at the stadium in the regular season, advised that attendees "take mass transit," to the game. "There's a bus—the NFL has organized that all over the town," he added.

With thousands of people—many of them not residents of the metropolitan area—waiting in lines for public transit and going through security checks, the logistics surrounding the game have been complex.

In an interview with CNBC on Thursday, former NFL quarterback Joe Theismann said, "I'm very curious to see how smoothly that runs."

The FBI reported Friday that hotels and other locations near the stadium had received suspicious letters and packages. But initial tests showed the items were not hazardous, NBC News reported.
