Issues for Integrity: Bridge Collapse in Arizona Is Averted Thanks to the Right Equipment

Tennessee's bridge inspection program is one of four state programs to demonstrate that it has inspected all its bridges on schedule, according to a recent independent analysis. The analysis used National Bridge Inventory records, which included inspections up to 2006 and reported that at least 17,000 bridges in the U.S. had gone more than two years between safety inspections. The state ranks 10th in the U.S. in number of bridges, with 19,560 that it has to inspect on the National Highway System or on local system, the most of any of the states with perfect on-time inspection records. The vast majority of Tennessee's bridges are straightforward in design and relatively accessible, ranging from as short as 20 feet to longer than 1,000. In 2008, the state will spend $36.2 million to repair some 69 bridges. About 80 percent of the money comes from federal sources. The inspection work is done by 17 inspection teams within the Tennessee Department of Transportation.
