The United States has one of the most extensive roadway systems in the world. Residents enjoy fast and direct travel by personal vehicle from journey's beginning to end. A major factor in enabling such effectual commuting is our bridges. Consider how often the average person passes over a bridge in any given daily commute. Such bridges may be massive steel goliaths or they may be smaller spans used for going over a ditch or stream.
A lot can go into building a modern bridge. An extensive amount of time and attention to detail is spent on planning. Many resources, both material and human, are used in the actual construction but, bridge work doesn't end there. Bridges require routine inspection and maintenance to ensure safety. Guidelines set by the NBIS require bridge inspections every two years. The sheer number of bridges makes this formidable undertaking.
Inspection teams survey a bridge's condition. They can spot signs of corrosion and signs of potential dilapidation. An inspection often involves a variety of bridge surveying equipment and a surveying truck. When they detect corrosion on a bridge or overpass an inspector can report it and the problem can be resolved quickly to reduce the amount of time the problem poses a potential risk.
Thanks to regular NBIS bridge analysis United States bridges are being repaired more effectively. That kind of mandated NBIS analysis means a safer drive for everyone. Motorists can take confidence knowing overpasses and bridges are being monitored. Drivers can take confidence knowing bridges and overpasses are being held to rigorous standards.
