The United States maintains one of the most large-scale road networks in the world. Residents enjoy swift and direct travel by personal vehicle from point A to point B. 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.
Much can go into constructing a bridge. An extensive amount 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 ensure safety. NBIS require bridge inspections every two years. The sheer number of bridges makes this quite the undertaking.
Inspectors analyze a bridge's condition. They can spot signs of corrosion and overall structural integrity. An NBIS inspection usually involves an array of bridge inspection devices and including an analysis vehicle.
Thanks to routine checks by NBIS compliant bridge inspectors US bridges are being improved more efficiently. That kind of regulated NBIS bridge maintenance means a safer drive for everyone.
