Security to be tight on National Mall for Independence Day

Tomorrow, hundreds of thousands of people will be gathered in and around the National Mall to celebrate America's Independence.

But to get there, you're going to have to go through a little extra security.

The long lines will soon form for tomorrow's Capitol Concert, but only 15,000 people will be let in. And absolutely no one will escape detection. Several metal detectors have already been erected.

U.S. Capitol Police say they'll search for: "Sharp objects, such as knives, those are not allowed. Fireworks as well. Alcoholic beverages are prohibited."

Police say security is always tight, but the Boston Marathon bombing changed things this year.

But 14,000 linear feet of bike rack barriers will keep the crowds at bay. So will 18,000 feet of chain link fencing.

And with thousands more trying to see the rockets red glare on the Mall, U.S. Park Police say expect equally tight security with nine checkpoints where they’ll screen backpacks, coolers, and anything you bring.

Police say the access points will open at 10 a.m. No one will be allowed in earlier and there will be no camping out in advance.

Rains have already turned the Mall into a muddy mess. It’s not likely to dry out by tomorrow, so beware.

Park Police say if you're headed to the Mall, they want you to sign up for the emergency notification system. You can text july4dc to 8-8-8-7-7-7 and you're signed up.
