Millions expected to travel 4th of July weekend

If you're planning to spend this holiday weekend away from home, expect crowded airports and longer security lines, or to sit in bumper-to-bumper traffic with millions of other people.

"We are projecting that 43 million Americans are going to be traveling this holiday season," Tamra Johnson with AAA said.

AAA expects more than three million Texans will travel during the Fourth of July holiday weekend and most will drive.

A big reason why so many will hit the road is that gas prices are cheapest now than they've been in a decade. The average price of gas in Texas is $2.12 for a gallon of regular unleaded fuel, according to the AAA Texas Weekend Gas Watch.

"We continue to encourage the public to travel, to associate, to celebrate the July 4th holiday. But be aware and be vigilant," Homeland Security Secretary Jeh Johnson said.

Law enforcement and other government agencies are beefing up security across the country this weekend, especially at airports, train stations, and other public venues.

On the roads, July 4th is said to be the deadliest day of the year for drivers, according to the Insurance Institute for Highway Safety.
