National Bridge Inventory - Issues and Usage

Issues and Usage

The NBI was subjected to scrutiny and questions, after new actions revealed it might be outdated or inaccurate. Federal officials attempted to order emergency inspections of all steel truss bridges after a major bridge collapse in Minneapolis in 2007. However, it was found that many records within the NBI were inaccurate or out of date.

The Inventory is used for federal funding purposes. A "bridge sufficiency rating" is calculated, based 55% on the structural evaluation, 30% on the obsolescence of its design, and 15% on its importance to the public. As of 2008, a score of 80 or less is required for federal repair funding, and 50 or less for federal replacement funding.

Famous quotes containing the words issues and/or usage:

    Your toddler will be “good” if he feels like doing what you happen to want him to do and does not happen to feel like doing anything you would dislike. With a little cleverness you can organize life as a whole, and issues in particular, so that you both want the same thing most of the time.
    Penelope Leach (20th century)

    ...Often the accurate answer to a usage question begins, “It depends.” And what it depends on most often is where you are, who you are, who your listeners or readers are, and what your purpose in speaking or writing is.
    Kenneth G. Wilson (b. 1923)
