The U.S. is home to one of the most extensive roadway networks in the world. We benefit from swift and unobstructed travel by personal vehicle from journey's beginning to end. A primary factor in enabling such effectual commuting is our bridges. Just consider how often the average driver passes over a bridge in any given day. These bridges may be large steel goliaths or they may be smaller spans used for crossing a creek or ditch.
Much can go into building a modern bridge. An extensive amount 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 periodic analyzing and maintenance to safeguard against hazards. NBIS regulations for maintenance require bridge inspections every two years. Due to the massive array of bridges in use, this becomes a challenging undertaking.
Inspectors survey a bridge's condition. They can spot items in need of repair and design flaws. A bridge inspector will often carry an array of surveying devices as well as a bridge surveying vehicle. Every time they detect weaknesses on a overpass or bridge an inspector can report it and the issue can be repaired swiftly to reduce the length of time the problem poses a potential risk.
Thanks to regular inspections United States bridges are being improved more efficiently. That sort of regulated NBIS maintenance means a safer drive for everyone. Drivers can enjoy a little more peace of mind knowing bridges and overpasses are being held to rigorous standards.
