摘要：	This synthesis focuses on overweight vehicle bridge permit processes. Information on state and provincial bridge rating systems, bridge evaluation practices and permit policies as they relate to overweight and oversize vehicles is highlighted and discussed. This report is intended to assist in the understanding of the reasons for non-uniform permitting practices. The report reviews specifications, software types, treatment of nonstandard configurations, and allowance for in-place dead loads; processes of permit review; and personnel assigned to permit review. A survey was distributed to transportation agencies at the state level in the United States and to Canadian provinces. A literature search was undertaken to identify relevant research reports, papers, and other publications for review and summation. Additional information was acquired from telephone interviews with targeted individuals and organizations to supplement the survey and literature search. The members of the topic panel are acknowledged on the preceding page. This synthesis is an immediately useful document that records the practices that were acceptable within the limitations of the knowledge available at the time of its preparation. As progress in research and practice continues, new knowledge will be added to that now at hand.
