Tolls are a direct user fee charged for use of facility capacity and services. Historically, toll roads played a prominent role in the provision of road transportation in the eighteenth and nineteenth centuries. In the first half of the nineteenth century, it is thought that private toll roads outnumbered public roads in the United States. Private investors formed tollway companies that improved, constructed, and maintained roads and, in turn, charged the public for their use.
In the late nineteenth century, toll road development tapered as toll evasion as well as rail travel increased. However, by the 1930s, some states began developing public toll road programs to respond to growth in automobile ownership, the rising needs of commerce, and the absence of significant Federal-aid for highways. While private tollway companies dominated the "turnpike" industry in the earlier centuries, the toll facilities of the twentieth century have largely been authorized, constructed, and managed by quasi-public authorities established by state and local governments. The pursuit of toll roads declined again after 1956, when the Federal-aid Highway Act established a Federal motor fuel tax to support the interstate highway system and prohibited tolling on new, Federally-funded highways.
Today, public funding constraints have fueled new interest in tolls as a revenue source to support transportation investment. Interest in toll roads today is largely an outgrowth of more supportive regulations beginning in 1991 with ISTEA that have liberalized and incentivized the use of Federal-aid in conjunction with private resources for road development purposes. Public-private partnership development of toll roads has been the focus of most state DOT activities in privatization.
Federal tolling programs first launched by ISTEA have also expanded through subsequent Federal-aid authorization acts, including the 2012 Moving Ahead for Progress in the 21st Century (MAP-21) Act's mainstream and pilot toll programs, now continued under the 2015 Fixing America's Surface Transportation (FAST) Act and 2021 Bipartisan Infrastructure Law. The FHWA Center for Innovative Finance Support manages these toll programs.
Toll organizations use a variety of funding sources, although the two most common are toll charges and revenue bonds. These funding sources are closely linked, in that future toll revenues are typically pledged as the security for bonds issued to construct, maintain, expand, or operate the associated toll facility(ies) and are used to make bond principal and interest payments.
Today, many state transportation agencies see toll facilities as a way to close funding gaps for transportation projects in a time of constrained public resources. Specifically, tolling can promote the following benefits in transportation spending:
Toll facilities were traditionally associated with long queues and high emissions at collection points, but these disadvantages are disappearing with electronic toll collection at toll booths or in overhead gantries and/or the pavement. Still, toll roads and bridges face other challenges, including:

IBTTA: International Bridge, Tunnel and Turnpike Association
The IBTTA is the industry organization representing tolling entities and the engineering, construction, and financial corporations that support them. It has an international membership and maintains a member address directory and serves as an information clearinghouse and research center. It also conducts surveys and studies and publishes a variety of reports, statistics, and analyses.
