Motorists hitting the road for the Thanksgiving holiday will encounter slightly fewer deficient and functionally obsolete bridges despite continued funding uncertainty, according to the Better Roads 2013 Bridge Inventory. Utah tied with Nevada for the second-fewest number of deficient bridges.
Structurally deficient (SD) and functionally obsolete (FO) are terms used by the U.S. Department of Transportation to describe bridges that do not meet current standards.
Of Utah’s 2,917 bridges, 8 percent were classified as functionally obsolete and 11 percent are structurally deficient.
In the survey of state road agencies, the District of Columbia reported a combined SD/FO rate of 57 percent, the highest in the nation. Rhode Island (51 percent), New York and Pennsylvania (tied at 39 percent) and Massachusetts (38 percent) round out those reporting the highest number of bridges designated as either SD or FO.
