Aging infrastructure
• American Association of State Highway and transportation Officials (AASHTO)
• Issued report on 8/1/08 "Bridging the Gap: Restoring and Repairing the Nation's Bridges."
![Page 20: Transportation infrastructure: Are bridges an area of concern? Ryan Church and Jason Mumbach September 17, 2008](https://reader035.vdocuments.us/reader035/viewer/2022062805/5697c00c1a28abf838cc89de/html5/thumbnails/20.jpg)
Aging infrastructure
• Average age of the country’s bridges is 43 years, with most bridges built to last 50 years
• 152,316 of the nation's 599,766 bridges are "structurally deficient" or functionally obsolete. (1 in 4)
• Estimates that repairing or modernizing bridges across the country would cost $140 billion
![Page 21: Transportation infrastructure: Are bridges an area of concern? Ryan Church and Jason Mumbach September 17, 2008](https://reader035.vdocuments.us/reader035/viewer/2022062805/5697c00c1a28abf838cc89de/html5/thumbnails/21.jpg)
Aging infrastructure
• United states spends $80 billion a year
• The National Surface Transportation Policy and Revenue Study Commission has estimated that the U.S. should be spending about $225 billion a year –
• That’s $225 billion for the next 50 years to upgrade its transportation infrastructure.

Aging infrastructure
• Age and Deterioration - The nation has a generation of Baby Boomer Bridges, constructed in the 1950s and 1960s, that need major repair or replacement.
• Usually built to last 50 years, the average bridge in this country today is 43 years old.
![Page 23: Transportation infrastructure: Are bridges an area of concern? Ryan Church and Jason Mumbach September 17, 2008](https://reader035.vdocuments.us/reader035/viewer/2022062805/5697c00c1a28abf838cc89de/html5/thumbnails/23.jpg)
Aging infrastructure
• While safe to travel, almost one in four bridges is either structurally deficient and in need of repair, or functionally obsolete and too narrow for today’s traffic volumes.
