Current levels of available resources to maintain and preserve the Pennsylvania short-line railroad bridge infrastructure require that important priority decisions be made on an annual basis. The primary objective of the study was to establish a reliable database of Pennsylvania SLRR bridges and to develop a risk-based bridge prioritization algorithm. A bridge survey of Pennsylvania short-line railroad owners and operators was conducted to develop a bridge database that would be as complete and accurate as possible given the available time and resources. The proposed algorithm provides a tool for PennDOT to use in making more effective maintenance and preservation resource allocation decisions for these structures. The study consisted of a literature review, bridge survey, database update, bridge sample, assessment of the current overall SLRR bridge population, and a risk-based prioritization algorithm.
