With July 4 falling on a Thursday, slightly fewer motorists plan to travel 50 miles or more over the Independence Day holiday, AAA estimates.
A news release from the agency said travelers in Oregon, California, Washington, Hawaii and Alaska can expect a slight dip in traffic, compared with last year. The predicted 6.3 million people on the road is down 0.7 percent from 2012 numbers.
AAA officials say a shorter holiday period is the main reason for the slight drop, but that increased gas and motel prices also contribute slightly.
July 3 and 7 are expected to be the busiest travel dates.
