They are starting to fence the blocks on Super Bowl City for its scheduled opening on Saturday. To ensure safety for football fans, security experts started to beef up the security features of the facility.

This year's Super Bowl will be held at Levi Stadium and federal agents are transforming the place into a formidable fortress. In San Francisco, security officials are installing fences in the main venue and will be using metal detectors to discourage trouble makers from coming in. The place will also be used for the pre-game festivities that usually come with the Super Bowl.

This event is expected to cost the San Francisco police and fire departments, along with its emergency management department a lot of money, . Unfortunately, it appears that the NFL is not reimbursing them for the expense that they will incur as host to the events related to the game.

According to the city's budget officials, the city is expected to spend approximately $4.8 million for the nine days that it will play host to the pre-Super Bowl event next month.

These expenses, according to an analysis that was reported in San Francisco Examiner, are money that are often unaccounted for. Still, those who promote the NFL claim that the game benefits the city which hosts it.

Actually, it is not San Francisco that is hosting the game. The game will be played in Levi Stadium, which is located in Santa Clara. But the city will only host the related events associated with the NFL's "Super Bowl City" festivities.

The greatest expense will come from the city's transportation department, which expects to spend around $2.3 million. But the city hopes to get back some of the money by way of additional public transportation fares.

The city's police department expects to incur $1.5 million expenses, while the fire department, about $600,000. All these monies will be shouldered by taxpayers.
