Our nation is home to one of the most extensive road networks in the world. Residents benefit from speedy and direct travel by personal vehicle from journey's beginning to end. A considerable factor in facilitating such effectual commuting is our bridges. Consider how often the average commuter passes over a bridge in any given day. Such bridges may be large steel giants or they may be smaller spans used for crossing a ditch or stream.
Much can go into erecting a modern bridge. An extensive amount of time and attention to detail is spent on design. Many resources, both material and human, are used in the actual construction but, bridge work doesn't end there. Bridges require regular analyzing and maintenance to safeguard against dangers. Guidelines set by the NBIS require bridge inspections every other year. The sheer number of bridges makes this quite the task.
Inspectors analyze a bridge's condition. They can spot signs of corrosion and unforeseen effects local environment is having upon the structure. An NBIS bridge inspector will usually have a variety of analysis devices and including a surveying utility truck.
Thanks to routine bridge inspections United States bridges are being repaired more with more attention to safety. That kind of reliable NBIS bridge maintenance means a much safer drive for everyone.
