Federal Highway Administration (FHWA), U.S.A.
The Federal Highway Administration (FHWA) is a division of the United States Department of Transportation that specializes in highway transportation. The agency's major activities are grouped into two "programs," the Federal-aid Highway Program and the Federal Lands Highway Program. Its role had previously been performed by the Office of Road Inquiry, Office of Public Roads and the Bureau of Public Roads. FHWA's role in the Federal-aid Highway Program is to oversee federal funds used for constructing and maintaining the National Highway System (primarily Interstate Highways, U.S. Routes and most State Routes). This funding mostly comes from the federal gasoline tax and mostly goes to State departments of transportation. FHWA oversees projects using these funds to ensure that federal requirements for project eligibility, contract administration and construction standards are adhered to. Under the Federal Lands Highway Program, FHWA provides highway design and construction services for various federal land-management agencies, such as the Forest Service and the National Park Service. In addition to these programs, FHWA performs research in the areas of automobile safety, congestion, highway materials and construction methods.
