U.S. Deficient Bridges

Source: American Road & Transportation Builders Association (ARTBA), 2014

From the press release:
Data from a new government report show that if all the structurally deficient bridges in the United States were placed end-to-end, it would take you 25 hours driving 60 miles per hour to cross them. That’s like driving the 1,500 miles between Boston and Miami. And it’s a problem that’s close to home.

An analysis of the 2013 National Bridge Inventory database recently released by the U.S. Department of Transportation (USDOT) shows cars, trucks and school buses cross the nation’s more than 63,000 structurally compromised bridges 250 million times every day. The most heavily traveled are on the Interstate system.

The problem could get a lot worse, the chief economist for the American Road & Transportation Builders Association (ARTBA) says, as states across the nation face a slowdown in reimbursements for already approved federal-aid highway projects in August. Without congressional action, Dr. Alison Premo Black says there will be no Highway Trust Fund support for any new road, bridge, or public transportation projects in any state during FY 2015, which begins October 1….

….The ARTBA analysis of the bridge data supplied by the states to the USDOT found:
– The 250 most heavily crossed structurally deficient bridges are on urban interstate highways, particularly in California. With one exception, all are at least 39 years old.
– Pennsylvania (5,218), Iowa (5,043), Oklahoma (4,227), Missouri (3,357) and California (2,769) have the highest number of structurally deficient bridges; Nevada (36), Delaware (56), Utah (117), Alaska (133) and Hawaii (144), the least.
– At least 20 percent of the bridges in four states—Pennsylvania (23 percent), Rhode Island (22 percent), Iowa (21 percent) and South Dakota (21 percent)—fall in the structurally deficient category…..
