Senators Murphy (D) and Corker (R) Propose 12-Cent Gas Tax Increase

There are several proposals on the table to stave off the impending insolvency of the Highway Trust Fund (which pays for transit, biking, and walking projects too) in two months. Just now, two senators teamed up to announce one that might actually have a chance.

Sens. Bob Corker (R-TN) and Chris Murphy (D-CT) have proposed increasing the gas tax by 12 cents a gallon over two years. The federal gas tax currently stands at 18.4 cents a gallon, where it has been set since 1993, when gas cost $1.16 a gallon. The senators' proposal would also extend some expiring tax cuts as a way to reduce the impact on Americans.

"I know raising the gas tax isn’t an easy choice, but we’re not elected to make easy decisions – we’re elected to make the hard ones," said Murphy. "This modest increase will pay dividends in the long run and I encourage my colleagues to get behind this bipartisan proposal.”

This proposal -- while still not introduced as a formal bill -- has far more potential than anything else that's been offered. President Obama's corporate tax scheme was dead on arrival, even though it had support from the Republican chair of the Ways and Means Committee, Dave Camp. Rep. Peter DeFazio's idea of a per-barrel oil fee and Sen. Barbara Boxer's idea for a wholesale oil tax don't have Republican support. Neither does Rep. Earl Blumenauer's 15-cent gas tax hike, which was the most logical proposal on the table, until now. What the House Republicans want to do is fund the transportation bill by reducing Saturday postal service -- a hare-brained scheme if ever there was one.

What gives this proposal a fighting chance, of course, is Bob Corker's name on it. Not only is Corker a Republican, but he's a respected leader on the Banking Committee. It's also a sign that maybe, just maybe, as we stare down the barrel of a real funding shortfall, members of Congress might find the gumption to do what they all know needs to be done: raise the gas tax.

“In Washington, far too often, we huff and puff about paying for proposals that are unpopular, yet throw future generations under the bus when public pressure mounts on popular proposals that have broad support," said Corker. "Congress should be embarrassed that it has played chicken with the Highway Trust Fund and allowed it to become one of the largest budgeting failures in the federal government. If Americans feel that having modern roads and bridges is important then Congress should have the courage to pay for it.”

The CBO has said that a one-cent increase in the gas tax would net $1.5 billion a year. That means this 12-cent increase would bring in exactly the $18 billion needed annually to fund the Senate's six-year transportation bill. And perhaps most importantly, Corker and Murphy propose indexing the tax to inflation so it remains viable in the future.

"A return to stable funding will ensure that our states and communities can repair aging roads, bridges and transit systems and build the infrastructure we need for a growing economy," said James Corless, director of Transportation for America, in a statement. "The alternative is to allow our transportation system to crumble along with an economy hobbled by crapshoot commutes and clogged freight corridors."

The president and CEO of AAA, which just came out in favor of a gas tax increase, agreed. "Many Americans are willing to pay a little more if it will lead to improved transportation and a better commute,” said Bob Darbelnet in a statement.
