The United States is home to one of the most large-scale road networks in the world. We benefit from speedy and unobstructed travel by personal vehicle from point A to point B. A major factor in facilitating such effectual commuting is our bridges. Just consider how often the average person passes over a bridge in any given daily commute. These bridges may be massive steel goliaths or they may be smaller spans used for crossing a creek or ditch.
A lot 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 routine analyzing and maintenance to ensure safety. NBIS bridge inspection guidelines mandate bridge inspections every other year. Due to the massive array of bridges in use, this becomes quite the task.
Inspection teams analyze a bridge's condition. They can spot items in need of repair and unforeseen effects local environment is having upon the structure. A bridge inspector will often carry an array of surveying devices and including a surveying truck. When they detect corrosion on a overpass or bridge a bridge inspector can make a report and the problem can be addressed quickly to reduce the length of time the problem poses a safety issue.
Thanks to routine inspections United States bridges are being attended to more with more attention to detail. That kind of mandated bridge maintenance means a safer drive for everyone. Motorists can take confidence knowing overpasses and bridges are being monitored.
