With more than 100 colleagues joining him in urging the tax policy committee to ensure the solvency of the Highway Trust Fund this year, the leader of the subcommittee on highways is continuing to push for sustainable funding for infrastructure projects as Congress turns its attention to reforming tax policy.

An overhaul of tax policy should include a long-term solution for the Highway Trust Fund, the top authorizers of highway projects plan to say to their tax policy counterparts.

Transportation bills introduced in both houses of the South Carolina Statehouse aim to address the state’s $1.2 billion infrastructure funding shortfall and succeed where a  House-approved $4 billion transportation funding measure failed to pass in the Senate last year.

Colorado’s Department of Transportation has a $9 billion funding shortfall. That can be blamed partly on the state’s failure to raise its taxes of 20.5 cents per gallon on diesel and 22 cents on gasoline since 1992.

Tennessee hasn’t raised its taxes of 18.4 cents per gallon on diesel and 21.4 cents per gallon on gas since 1989. The decision not to index those taxes to the rate of inflation along with the spread of increasingly fuel-efficient vehicles has caused a funding shortfall that the state’s Department of Transportation estimates at $6 billion.

Mississippi’s Department of Transportation says it has a $526 million funding shortfall. That figure has only grown because of the drought that began in late summer and extended for most of the fall.

MADISON, Wis. — With Republicans taking full control in Washington, GOP governors across the nation will seek a bedrock shift in how the federal government helps states pay for highway projects, worker training and health care for the needy.
