Our nation offers one of the most extensive road systems in the world. Residents benefit from fast and direct travel by personal vehicle from point A to point B. A primary factor in enabling such efficient commuting is our nation's bridges. Just consider how often the average commuter passes over a bridge in any given daily commute. These bridges may be large steel goliaths or they may be smaller spans used for going over a creek or ditch.
Much can go into constructing a bridge. Vast amounts of time and attention to detail is spent on specs. Many resources, human and material, are used in the actual construction but, bridge work doesn't end there. Bridges require periodic inspection and maintenance to safeguard against hazards. NBIS guidelines for maintenance mandate bridge inspections every two years. The sheer number of bridges makes this quite the undertaking.
Inspectors survey a bridge's condition. They can spot maintenance needs and design flaws. An inspector will usually carry a variety of analysis tools and a surveying utility truck. Every time they observe corrosion on a overpass or bridge an inspector can make a report and the problem can be repaired swiftly to minimize the length of time the problem poses a potential risk.
Due to routine bridge inspections US bridges are being improved more effectively. That kind of reliable analysis means a much safer drive for everyone. Motorists can take confidence knowing bridges and overpasses are being monitored.
