The Lagging Fuel Tax
The United States federal tax on fuel, first passed in 1932, is the funding source for new highway and bridge construction projects. It isn't tied to inflation and has not been increased since 1993, which has caused its buying power to shrink. It currently isn’t capable of funding the infrastructure that the United States needs. To make the fuel tax into an adequate funding source for infrastructure projects, it should be increased by at least 10 cents per gallon and indexed to both inflation and improvements in vehicle efficiency so that funding cannot lag decades behind the times again.
