The U.S. offers one of the most large-scale road networks in the world. We enjoy fast and direct travel by personal vehicle from point A to point B. A primary factor in enabling such effectual commuting is our bridges. Just consider how often the average driver passes over a bridge in any given day. These bridges may be massive steel giants or they may be smaller spans used for crossing a ditch or stream.
A lot can go into erecting a bridge. An extensive amount 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 routine inspection and maintenance to safeguard against hazards. NBIS mandate bridge inspections every 2 yrs. Due to the massive array of bridges in use, this becomes a challenging task.
Inspectors survey a bridge's condition. They can spot small issues and design flaws. An inspector will often carry a variety of inspection tools and a surveying utility truck. Every time they detect corrosion on a overpass or bridge an inspector can report it and the problem can be repaired quickly to minimize the amount of time the problem poses a safety issue.
Due to regular NBIS analysis United States bridges are being improved more effectively. That kind of regulated NBIS maintenance means a much safer drive for everyone. Motorists can take confidence knowing bridges and overpasses are being held to high standards.
