Our nation maintains one of the most extensive road 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 efficient commuting is our nation's bridges. Consider how often the average driver passes over a bridge in any given daily commute. These bridges may be massive steel goliaths or they may be smaller spans used for going over a creek or ditch.
A lot can go into building a modern bridge. Vast amounts of time and attention to detail is spent on design. Many resources, human and material, are used in the actual construction but, bridge work doesn't end there. Bridges require regular inspection and maintenance to ensure safety. Guidelines set by the NBIS require bridge inspections every two years. Due to the massive array of bridges in use, this becomes formidable undertaking.
Inspectors survey a bridge's condition. They can spot items in need of repair and design flaws. An NBIS inspector will usually carry an array of bridge inspection gear and including a bridge inspection truck. Every time they detect deterioration on a bridge or overpass an inspector can report it and the issue can be repaired swiftly to reduce the length of time the problem poses a safety issue.
Due to routine checks by NBIS compliant bridge inspectors United States bridges are being improved more effectively. That kind of regulated analysis means a much safer drive for everyone. Motorists can breathe easier knowing overpasses and bridges are being held to rigorous standards. Drivers can take confidence knowing overpasses and bridges are being monitored.
