The report says that the USA's bridges are usually built to last 50 years and that the average age today is 43. Almost 20% of what it calls 'baby boomer' bridges are more than 50 years old. AASHTO president and director of the Missouri Department of Transportation Pete Rahn said: "The current generation of baby boomer bridges are showing their age and they're going to require significant investment. We must act now."

The AASHTO report suggest solutions to the problems, including increased investment in transportation at all levels of government, support for a wide range of revenue options, continued commitment to research and innovation, systematic maintenance and increased public awareness that bridges are vital links to business and communities.
