The Highway Trust Fund (HTF), which serves as the clearinghouse for federal highway dollars, is once again facing a severe shortfall. It is expected to run dry unless it receives a $5 to $7 billion cash infusion from the federal government by August.

Given President Obama's emphasis on infrastructure investment, Congress is unlikely to let the HTF flounder. Yet, supplying the cash is clearly a "Band-Aid" approach. It fails to address the real problem - the inability to ensure ongoing revenue generation long term.

We are likely to see shortfalls in HTF funds for years to come unless a more permanent fix is put in place. The American Road & Transportation Builders Association (ARTBA) is already estimating that the current $41 billion highway program funding level for FY 2010 will necessitate a further $10 billion trust fund revenue infusion next summer.

In testimony before the U.S. House Subcommittees on Special Measures and Oversight, Committee on Ways and Means, Bill Buechner, ARTBA vice president, economics and research, cited the reasons behind the HTF funding gap as: the siphoning of both revenue and interest income from the HTF in the '90s to bolster the General Fund; the failure to increase the federal motor fuels tax since 1993; rising highway construction costs; and a reduction in fuel purchases over the past year.

Both the National Surface Transportation Infrastructure Financing Commission and the National Surface Transportation Policy and Revenue Study Commission have concluded the most efficient way to increase needed HTF revenue is to raise the federal gas and diesel tax rates, then index them annually to inflation, Buechner reports. Longer term, the commissions recommend the transition to a vehicle-miles-traveled (VMT) based user fee system.
