NEW YORK - Gas prices are expected to be lower in certain parts of the country for July 4th.

The national average for a gallon of gas is just below $3.50 a gallon because gas supply is up while consumer demand is down. AAA says this year's prices however are still the third highest on record for Independence Day, right behind $3.57 a gallon in 2011.

The highest gas prices can be found in West Coast states like California and Washington, while southern states like Alabama and South Carolina are the cheapest.
