摘要：	This report of the Transportation Research Board examines off-system bridge design, construction, maintenance, financing, rehabilitation, and replacement. For this report off-system refers to those bridges typically owned and maintained by local agencies and by state agencies on rural and other low-volume roads. It will be of interest to all state departments of transportation and local agencies with off-system bridges under their jurisdiction. The report focuses on the best procedures that promote safe, efficient and cost-effective practices for such bridges. Topics covered include the state of existing bridge populations, maintenance, load rating, rehabilitation, strengthening, geometrics, structural design criteria, replacement alternatives, construction practices, and off-system bridge administration, including funding, environmental permitting, and interagency cooperation and partnering. This synthesis contains information drawn from survey responses from U.S. state departments of transportation and local transportation agencies, a literature search and review, an owner survey, and a survey of bridge product producers.
