Bridges constitute one of the most important components of the highway infrastructure network in the United States. With nearly 600,000 bridges and culverts on highways ranging from multi-lane urban freeways to two-lane rural highways, the operation and functionality of the highway network greatly depends on the performance of these structures. Many initiatives towards improving bridge management have been undertaken, the latest being a program for long-term bridge performance (LTBP) incorporated in the recently approved highway. While the LTBP program provides funding and a general mechanism for effective management of bridges, the details of its thrust and its components are yet to be established. The overall objective of the proposed workshop is to bring together bridge owners, federal policy makers, researchers, national experts, and international experts in one physical location with the ultimate goal of formulating a roadmap for the future direction and activities of the long-term bridge performance program. A two-day meeting to be held in early 2007 is proposed. It is envisioned that at the conclusion of the workshop an insightful, thorough, and practical report is compiled that essentially captures all the key discussions and recommendations. The proposed workshop and the recommendations that will result from the workshops are of pivotal importance to the US highway bridge safety and economy. The collective wisdom of the workshop participants will set the trends and directions that FHWA, NSF, and state departments of transportation will follow in near and long terms with respect to research, field implementation, monitoring, assessment, decision process, and bridge management. Effective and visionary expenditure of the funds for the initial phase of the program could help facilitate the allocation of federal budget for future phases, with the end result being safer, more reliable, and more economical bridges that utilize the latest technologies.

桥梁是美国公路基础设施网络中最重要的组成部分之一。从多车道的城市高速公路到两车道的农村高速公路，高速公路上有近60万个桥梁和涵洞，公路网的运行和功能在很大程度上取决于这些结构的性能。已经采取了许多改善桥梁管理的举措，最近的一项计划是将长期桥梁性能（LTBP）纳入最近批准的高速公路。虽然LTBP计划提供资金和有效管理桥梁的一般机制，但其重点和组成部分的细节尚未确定。提议的研讨会的总体目标是将桥梁业主、联邦政策制定者、研究人员、国家专家和国际专家聚集在一个物理地点，最终目标是为长期桥梁性能计划的未来方向和活动制定路线图。建议于2007年初举行为期两天的会议。预计在讲习班结束时，将编写一份有见地、全面和实用的报告，基本上涵盖所有关键的讨论和建议。拟建的研讨会以及研讨会提出的建议对美国公路桥梁的安全和经济至关重要。研讨会参与者的集体智慧将为FHWA、NSF和州交通部门在近期和长期的研究、实地实施、监测、评估、决策过程和桥梁管理方面设定趋势和方向。有效和有远见地支出该项目初始阶段的资金，有助于促进联邦预算在未来阶段的分配，最终结果是使用最新技术的桥梁更安全、更可靠、更经济。
