This paper presents the results of a study using Louisiana's National Bridge Inventory (NBI) to determine matrices of the deterioration of bridge components (elements) that can be used in Pontis software. These matrices are for a simplified three-element bridge preservation model the authors developed for the Louisiana Department of Transportation and Development. The results indicate that the deterioration of bridge components does not correlate well with the age of bridges and that the Markov transition probability is a good tool for predicting bridge deterioration. When using state NBI data to generate Markov matrices of bridge components' deterioration, the resulting probabilities will be affected by the average bridge age in the database and the time intervals depending upon which NBI data are initially analyzed. This fact should be considered in the use of these deterioration matrices for predicting future bridge deterioration.
