The National Bridge Inventory or NBI simplifies complex nationwide bridge repair programs by maintaining a comprehensive database on the condition of highway bridges across the U.S. This entitles state transportation agencies to prioritize urgent repairs, allocate funding judiciously, and monitor bridge infrastructure health. For the most part, the National Bridge Inventory assists in making data-driven decisions for maintenance, repair, and recovery projects.

Let’s Find Out the How National Bridge Inventory helps with Bridge Repairs.

Elaborative Bridge Data: The National Bridge Inventory fetches and saves detailed information about each bridge, including its structural components, condition ratings, inspection reports, and any other identified limitations or defects. This allows federal administrations to target repair strategies.

Prioritization and Scheduling of Repairs: By analyzing the National Bridge Inventory data, federal administrations can recognize bridges in the most critical condition and order them for repair or replacement. With such information, states can clinch that the most called-for projects are addressed first.

Allocation of Funds: For the most part, the National Bridge Inventory data helps the U.S. Department of Transportation account for funding requests for bridge repairs to federal authorities by determining and validating the severity of bridge conditions.

Analyzing Trends: By monitoring bridge conditions over time through recurring inspections, the National Bridge Inventory enables the analysis of deterioration patterns. In particular, it allows progressive predictions of future maintenance requirements and power-packed planning.

Risk-based Approach: The National Bridge Inventory accredits a risk-based approach to bridge maintenance. In this case, bridges with a higher potential for damage, disruption, or failure due to traffic volume or deteriorating conditions receive greater attention.

Why is the National Bridge Inventory Valuable in Bridge Repairs and Replacements?

Operations and Maintenance

The United States’ bridges comprise a vast and complex system of unique infrastructure. However, many of these structures are deteriorating over time and need specific management at specific times. To manage this large span of assets, federal authorities are now required to develop and use Transportation Asset Management Plans.

These federally essential TAMPs define a systematic, data-based approach for the administration to manage their bridge inventories. Each TAMP is required to speculate and set targets for the bridges that will be in good, satisfactory, or poor condition over the next 10 years. Above all, strategic asset management is one of the most economical ways to address aging or deteriorating bridge inventory.

Public Safety and Resilience

Next, a systematic and risk-based approach is necessary to make bridged more resilient whenever the investments are made. Many of the country’s older bridges are at risk of damage and deterioration due to extreme weather events and more prevalent flooding. For the most part, this often results in overtopping, washout, and other storm-related damage.

Here, the National Bridge Inventory urges federal administrations to prioritize investments in bridges that are most critical or prone to damage or disruption. For example, those bridges that endure the highest daily traffic volume, are on critical or complicated freight corridors or are on evacuation routes, need multi-variable prioritization formulas. In such a case, NBI assists federal authorities in corroborating public safety and more resilient infrastructure than before.

On a Final Note,

National Bridge Inventory assists federal authorities and the U.S. Administration in increasing funding from all levels of government to continue outstanding bridge repair, replacement, and maintenance. Most importantly, prioritizing bridge rehabilitation and management helps preserve bridges in fair condition at a fraction of the cost of replacement if it is done on time. This approach knocks down the number of structurally deficient bridges to below 5%, reduces the maintenance backlog, and addresses bridges that have aged or are reaching the end of their design lifecycle.

Here, the National Bridge Inventory helps develop a balanced approach for the current aging bridge inventory. It emphasizes preservation, reconstruction, and replacement as and where required. Also, it set aside funding for critical operations and maintenance programs.

With the National Bridge Inventory, bridge owners or the federal authorities in the U.S. can smoothly consider the costs across a bridge’s entire lifecycle to make smart design decisions and prioritize repair, replacement, and maintenance.
