FHWA's bridge and structures R&D guidelines and specifications for the design, construction, evaluation, and preservation of bridges, tunnels, culverts, geotechnical constructions (e.g., walls, slopes, cuts, and fills) and other highway structures (e.g., sign structures); aerodynamic and hydraulic engineering guidance; design and mitigation guidance for extreme events (e.g., seismic, blast, and scour); advanced materials and structural systems; tools for the assessment and condition monitoring of highway structures; and data-driven performance management and preservation tools.
FHWA's bridge and structures research and development provides technologies and solutions to advance the state-of-the-art and practice in highway infrastructure engineering. FHWA's bridge and structures research is carried out as an integral part of FHWA's broader Infrastructure Research and Technology (R&T) Program. Accordingly, it contributes to agency-wide efforts to achieve the Agency's infrastructure R&T goals and strategic objectives.
To achieve these goals and objectives, the Office's three bridge and structures R&D teams conduct and manage research that enable an integrated, comprehensive, performance-based approach to facilitate the design, construction, and management of highway infrastructure. This includes developing: guidelines and specifications for design and construction of structural components and systems; tools and data to monitor and assess structural and functional performance; technologies and approaches that improve long-term durability and performance; and technologies and practices to withstand the effects of extreme events.
