The NBI also supports the requirements of the Highway Bridge Program, Title 23 USC Section 144, and 23 CFR 650D. The NBI follows specifications of the Recording and Coding Guide for the Structure Inventory and Appraisal of the Nation's Bridges. These standards are applicable to all highway bridges located on public roads. Data is collected from all 50 States, the District of Columbia, and Puerto Rico as well as Federal agencies which have bridges under their jurisdiction that are open to the public. Unit cost data pertaining to bridge replacement and rehabilitation, which is required to be collected by regulation, is also collected on an annual basis. A deficiency status is assigned to each bridge and an overall sufficiency rating calculated. Approximately 600,000 432-character bridge records are stored and maintained per year. The system contains data beginning in 1983. In addition, the NBI system interfaces with the Fiscal Management Information System (FMIS) in order to provide FMIS with valid bridge structure numbers for bridges eligible for Federal funding and to receive updated financial information for determining eligibility for the Highway Bridge Program. Access to the system is controlled by FHWA's User Profile Access Control System (UPACS) system. (N1-406-08-7)
