This is a print on demand edition of a hard to find publication. One in four bridges in the United States is either structurally deficient and in need of repair, or functionally obsolete and is not adequate for today's traffic. The Highway Bridge Program (HBP), the primary source of federal funding for bridges, provided about $7 billion to states in fiscal year 2010. This testimony addresses: (1) the current state of the nation's bridges and the impacts of the HBP; and (2) the extent to which the HBP aligns with principles developed to guide the re-examination of surface transportation programs. This testimony is based on prior reports, updated with bridge data and information provided by agency officials. Charts and tables.
