WSJ: U.S. Highway Fund Low on Cash Again

From WSJ:

The Obama administration said as much as $17 billion in additional federal money is needed to maintain roads and bridges over the next two years, underscoring the challenges policy makers face as driving habits change.  The recession and gas-price increases over the past two years have caused many consumers to drive less and switch to more fuel-efficient cars. The result has been a fall in revenue from taxes on gasoline and vehicle purchases, which are used to fund state and local transportation projects.  The highway trust fund will need an injection of as much as $7 billion by September or states would not receive all the money they are counting on to finance construction projects later this year, the administration said.
