Graphic: Highway funding from state, federal sources by state

In legislatures across the country, lawmakers and governors are confronting similar realities in their own states: how to address an aging network of roads, highways and bridges during an era in which federal money for such projects has remained stagnant or declined.

How we pay: Is gas tax out of date?

Figures compiled by The Associated Press show the total amount of money available to states from the Federal Highway Trust Fund has declined 3.5 percent during the five-year period ending in 2013, the latest year for which numbers were available. During that span, the amount of inflation-adjusted federal highway money dropped in all states but Alaska and New York.

In response, states have tried to devise ways to fill the gap. Governors and lawmakers in several states are proposing new taxes, tolls and fees to repair a road system whose historical reliance on fuel taxes no longer is providing enough money to cover its costs.
