A recently released study by the U.S. Department of Transportation (U.S. DOT) National Bridge Inventory database, reveals that nearly 61,000 bridges across the nation are classified as structurally deficient requiring significant repairs. Based on the data analysis carried out by the American Road & Transportation Builders Association (ARTBA) the 61,000 bridges are crossed by trucks, cars and other types of vehicles 215 million times every day, with the most heavily traveled ones being located along the Interstate Highway System. 

The government data analysis by the American Road & Transportation Builders Association (ARTBA) showed that the top three states with the highest number of structurally deficient bridges are Pennsylvania (5,050), Iowa (5,022) and Oklahoma (4,216), while Columbia (14), Nevada (34) and Delaware (48) presented the lowest rates. In addition, at least 15% of the bridges in eight states are categorized as structurally deficient, while nearly 87% of the most traveled bridges in need of structural repairs were constructed before 1970 along urban interstate highways. 

Dr Alison Premo Black, Chief Economist of the American Road & Transportation Builders Association (ARTBA) expressed her fears that the situation could get a lot worse in the future, as a result of five consecutive revenue deficits in the federal Highway Trust Fund (HTF), between 2008 and 2014, also being bailed out from the General Fund with nearly $65 billion in order to preserve existing investment levels. The continuing trust fund uncertainty has led about a dozen states to delay or even cancel road and bridge projects, with the ARTBA estimating that the number is likely to increase as the deadline for federal highway and transit funding through HTF approaches on May 31st.
