NEWARK, N.J. - With only hours to go until Super Bowl XLVIII kicks off, security around the event is at its highest levels of the week.

Security has been stepped up in and around MetLife Stadium in East Rutherford. Additional officers have been stationed at transit hubs in New York and New Jersey. 

The TSA brought in more than 20 bomb-sniffing dogs to Newark Liberty International Airport yesterday. The dogs are trained to sniff for explosives and will sit if they detect something, in order to avoid panic. Tens of thousands of visitors are expected to pass through for the game.

Travelers should anticipate bag searches. In addition, trains, cars and buses transporting fans will be scanned.

F-16 jets, fighter helicopters and police boats will also be patrolling the surrounding areas.
