Funding and Financing

Fuel tax revenues continue to decline nationwide, not only because of inflation and less driving, but also due to the growing use of fuel-efficient and alternative fuel vehicles. To learn how states are dealing with this issue, see our bill-tracking database, this November 2013 LegisBrief, our pages on toll facilities and taxation of alternative fuels, and the 2013 State Legislatures article "Pain at the Pump."


NCSL closely tracks how states are paying for and providing transportation projects. Explore our in-depth publications on state transportation governance and finance, innovative funding approaches and options for states, legislators’ infrastructure priorities, and related intergovernmental issues.


Public-private partnerships (PPPs or P3s) are agreements that allow the private sector to take on more responsibility and risk for infrastructure projects than is traditional—including, in some cases, private financing. As of 2014, 33 states and Puerto Rico have laws to authorize PPPs for roads and bridges. Read more in NCSL’s 2010 comprehensive report, 2014 update and other resources.


Check out our online, searchable Transportation Funding and Finance Legislation Database for information about state bills in 18 transportation funding and finance categories including gas taxes, per-mile charges, alternative fuel vehicles, local funding options and more.





America’s transportation infrastructure is at a crossroads. All states face a shortfall between existing transportation revenues and projected needs, with the cumulative nationwide shortfall estimated at $1 trillion through 2015.  Unless there are innovations and new money, roads, bridges and public transportation systems will continue to decline.

States are seeking both funding and finance options for transportation projects. Funding options include traditional revenues such as gas taxes and other taxes on motor fuels, motor vehicle fees and tolls, while less traditional approaches include per-mile charges and taxes on alternative fuels. States also are considering finance solutions that borrow against or otherwise leverage revenues, such as bonds, federal credit assistance, state infrastructure banks and public-private partnerships.
