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. 

With nearly 70,000 bridges requiring repair works across the U.S. and an estimated cost of $70 billion, Associate Professor's 3-D model aims in facilitating officials and transportation agencies to monitor the aging infrastructure more efficiently and prioritize the required repair works.

The Federal Highway Administration traveled to Pennsylvania last week to demonstrate the capabilities of their new million-dollar bridge inspection robot named RABIT (Robotic Assisted Bridge Inspection Tool).  The Federal Highway Administration chose to demonstrate the robot's capability in front of members of the Pennsylvania Department of Transportation because Pennsylvania has the most structurally deficient bridges of any state in the United States. The state is also home to the oldest bridges by average and has the third most bridges of any state. The FWHA believes that RABIT will become invaluable to DOTs around the country in the near future as a way to cut down on the manpower needed to inspect bridge decks.
