Our nation offers one of the most extensive roadway networks in the world. We enjoy speedy and uninhibited travel by personal vehicle from journey's beginning to end. A primary factor in enabling such efficient commuting is our bridges. Just consider how often the average driver crosses over a bridge in any given daily commute. Such bridges may be large steel giants or they may be smaller spans used for crossing a creek or ditch.
Much can go into erecting a modern 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 periodic inspection and maintenance to safeguard against hazards. Bridge maintenance guidelines mandate bridge inspections every other year. The sheer number of bridges makes this a challenging undertaking.
Inspectors analyze a bridge's condition. They can spot items in need of repair and design flaws. Bridge inspectors often have an array of surveying gear and including a bridge inspection vehicle.
Thanks to regular bridge analysis United States bridges are being repaired more efficiently. That kind of regulated NBIS analysis means a safer drive for everyone.
