Climate change impacts, such as more frequent and intense heat waves and flooding, threaten the considerable federal investment in transportation infrastructure. Given the long life span of transportation assets, planning for system preservation and safe operation under current and future conditions constitutes responsible risk management. FHWA has developed tools and information for states and regions to assess their vulnerabilities to climate change and improve resilience. FHWA is also integrating climate resilience into its programs. Summary of FHWA Climate Adaptation Initiatives
