A record-breaking number of Americans are expected to travel during the Independence Day holiday.

Triple-A says 48.9 million Americans are making plans for a 4th of July getaway.

Triple-A says this is the highest number since they began tracking holiday travel in 2000.

Travel volume is expected to rise by 4.1% over last year.

Triple-A cites lower gas prices, low unemployment, robust consumer spending, and rising disposable income as reasons for the increase in travelers.

The Pennsylvania Turnpike is preparing for more than six million travelers.

The more than 600,000 vehicles are expected to travel on the turnpike on each day between July 1 and July 5.
