Drivers who cross into South Carolina to buy cheaper gas could soon see that discount dry up.

The state needs more money for roads and some lawmakers want drivers to share in the cost.

Every time Joe Urey crosses into South Carolina, he makes sure to buy gas.

"If you're buying 10, 15, 20 gallons, it'd be silly not to get gas here," he said.

It's a big savings from purchasing gas in North Carolina – usually up to 20 cents cheaper per gallon.

Some Palmetto State House Republicans are proposing a change. They want to raise the gas tax by 10 cents a gallon to pay for state roads and bridges.

The increase could earn the state an extra $100 to $300 million per year.

"I think gas is already too high – the prices," said N.C. driver Vera McDonnell. "I feel like they got to do what they have to do to get the roads done, but I disagree."

For the first two years of the increased tax, only tourists, visitors and truckers would feed the burden because South Carolina residents would get a rebate. That means drivers who are just passing through will likely start making different choices.

"Their gas prices are high enough as they are now," said N.C. driver Kent Huggins. "No advantage now in S.C. versus N.C. and I just wish they were cheaper altogether."

Gov. Nikki Haley said she would veto any gas tax increase. She said the state can find the money by prioritizing in other areas.
