FHWAs

FHWAs, or the Federal Highway Administration, is a component of the United States Department of Transportation. The plural form is sometimes used to refer to the agency and its regional offices, though the agency itself is a single entity. Its core mission is to oversee the federal-aid highway program and to guide the development and operation of the national highway system, including the Interstate System.

The agency traces its origins to the Bureau of Public Roads, established in the early 20th century. In 1967, the Bureau was reorganized as the Federal Highway Administration, consolidating responsibilities for highways, bridges, and related infrastructure. The creation of the Interstate Highway System following the 1956 Federal-Aid Highway Act greatly expanded the FHWA's program and funding responsibilities.

Key responsibilities include administering federal funds for highway construction and maintenance, setting safety and design standards, conducting environmental reviews under the National Environmental Policy Act, and promoting research and innovation. The FHWA also oversees the manual on uniform traffic control devices and coordinates with state departments of transportation and local governments to implement federal requirements and standards.

Funding comes primarily from the Highway Trust Fund, supported by federal motor fuels taxes, with funds distributed to states through formula programs and optional or discretionary grants. The agency monitors compliance with federal requirements and provides technical assistance and oversight to state DOTs to ensure safety, mobility, and infrastructure quality.

Organization and locations: The FHWA is led by an Administrator, based in Washington, D.C., with regional and field offices across the country that work with state and local transportation agencies to deliver highway projects and improve transportation systems.
