America's Bridges May Be Falling Down Soon

cartechboy (2660665) writes "Oh dear. Turns out a recent analysis of data found in the National Bridge Inventory (yes, someone tracks bridge data) suggests we're in for a bit of trouble. The data: Of 607,380 bridges, 65,605 were classified as 'structurally deficient,' and 20,808 as 'fracture critical.' (If just one component on a fracture-critical bridge fails, it puts the bridge at risk of immediate collapse.) What's more, 7,795 bridges had both problems — a situation typically referred to as the 'double whammy.' Here is the translation of all the numbers: 13 percent of bridges in America are failing, and hundreds more will reach that state soon. How much will it take to address this? A mere $3.6 trillion, by the year 2020."
