Federal-Aid Highways: Information on State Use and Oversight of Engineering Consultants, Report to Congressional Committees [open pdf - 407KB]
From the Highlights: "The federal-aid highway program is the primary source of federal funding for projects that build and preserve the nation's roads and bridges. The Infrastructure Investment and Jobs Act authorized an average of about $54.6 billion annually for this program. FHWA [Federal Highway Administration] apportions this program's funding to state DOTs [departments of transportation] and provides oversight and technical assistance to them. State DOTs are generally responsible for implementing these federal-aid highway construction projects and are authorized by statute to contract with private engineering firms (engineering consultants) to help them do so. The Explanatory Statement accompanying the Further Consolidated Appropriations Act, 2020 included a provision for GAO [Government Accountability Office] to review state DOTs' use of engineering consultants for federally funded projects. This report describes (1) state DOTs' use of engineering consultants on federal-aid highway construction projects and the factors that affect their decisions to do so, and (2) how FHWA oversees state DOTs' use of engineering consultants on federal-aid highway construction projects, among other things."
