Some of the U.S. busiest bridges were built in the 1930s.
Recently, the U.S. Department of Transportation (USDOT) released an analysis of the 2013 National Bridge Inventory database, prepared by the American Road and Transportation Builders Association (ARTBA).
The main findings revolved around the fact that more than 63,000 bridges nationwide were structurally compromised. Despite that, they are being crossed by cars, school buses and trucks some 250 million times daily. Most of them are on the Interstate system.
Another interesting fact is that if all of those bridges were placed end-to-end, one needs to travel 25 hours with 60 miles per hour to cross them. It’s pretty much the same as the distance between Boston and Miami – 1,500 miles.
Unfortunately, there doesn’t seem to be an easy fix to this problem. Many states are already struggling with the slowdown in reimbursements for pre-approved federal-aid highway projects. Congressional push is needed in support of the Highway Trust Fund, so repairs on bridges and roads can begin.
Over the past 10 years, the Fund has secured $89 billion in bridge construction work done by the states.
