In the United States, the federal government primarily provides funding for interstate roads through the Federal Highway Administration (FHWA). The National Interstate and Defense Highways Act of 1956 established the Interstate Highway System, which is a network of highways designed to facilitate interstate travel and commerce. While the federal government sets standards and provides funding, state governments are responsible for the construction, maintenance, and operation of these roads.
