With higher gas prices pushing more people to take public transportation, the collection of gasoline taxes will decrease. This revenue is used to fund infrastructure, so the move to mass transit will put further strain on U.S. infrastructure investment. Additionally, the move to alternative fuels collects no tax, so it doesn’t pay for the roadway.

This Catch-22 was revealed by Patrick Natale, president of American Society of Civil Engineers, in an on-air interview (5 minutes) on CNBC. The subject of the discussion was whether there’s a silver lining to $4 gas. While higher gas prices will reduce emissions, we’ll need to turn to other funding mechanisms in order to keep up with declining infrastructure.

The experts suggested that we’ll need to turn to more public/private partnerships and create more toll roads in order to deal with the shortfall in funds. With the economy slumping, there’s little political will to increase taxes to further compound the financial pinch that most Americans are feeling.
