Our nation is home to one of the most extensive roadway networks in the world. Residents benefit from swift and uninhibited travel by personal vehicle from journey's beginning to end. A primary factor in facilitating such efficient commuting is our bridges. Consider how often the average person crosses over a bridge in any given day. These bridges may be large steel goliaths or they may be smaller spans used for going over a ditch or stream.
Much can go into erecting a modern bridge. Vast amounts of time and attention to detail is spent on planning. Many resources, both material and human, are used in the actual construction but, bridge work doesn't end there. Bridges require routine analyzing and maintenance to safeguard against dangers. Guidelines set by the NBIS call for bridge inspections every 2 yrs. The sheer number of bridges makes this a challenging task.
Inspection teams survey a bridge's condition. They can spot maintenance needs and unforeseen effects local environment is having upon the structure. A bridge inspector will usually carry a variety of inspection tools as well as a bridge inspection vehicle.
Thanks to regular NBIS analysis United States bridges are being maintained more efficiently. That sort of code compliant NBIS maintenance means a safer drive for everyone.
