The United States offers one of the most large-scale roadway networks in the world. We enjoy swift and direct travel by personal vehicle from journey's beginning to end. A considerable factor in facilitating such effectual commuting is our bridges. Just consider how often the average driver crosses over a bridge in any given daily commute. These bridges may be large steel goliaths or they may be smaller spans used for going over a creek or ditch.
Much can go into constructing a modern bridge. Vast amounts of time and attention to detail is spent on specs. Many resources, both material and human, are used in the actual construction but, bridge work doesn't end there. Bridges require periodic inspection and maintenance to ensure safety. NBIS regulations for maintenance require bridge inspections every 2 yrs. Due to the massive array of bridges in use, this becomes formidable undertaking.
Inspectors survey a bridge's condition. They can spot small issues and signs of potential dilapidation. An NBIS bridge inspector will usually carry a variety of bridge surveying devices and including an analysis vehicle.
Due to regular NBIS analysis United States bridges are being improved more efficiently. That kind of mandated bridge analysis means a safer drive for everyone.
