Wisconsin Bridge Inventory

This Feature Service provides detailed geospatial data on bridges located on public roads within the state of Wisconsin. It is sourced from the Federal Highway Administration (FHWA) and forms part of the U.S. Department of Transportation's National Transportation Atlas Database (NTAD). Key aspects of the dataset include: Comprehensive bridge identification and classification, including unique structure numbers and route information. Structural characteristics such as bridge type, length, width, number of spans, and clearance measurements. Condition assessments covering deck, superstructure, substructure, and other critical components. Inspection and maintenance records detailing inspection dates and frequency. Traffic data including average daily traffic volumes and truck percentages. Ownership and maintenance agency information. This dataset supports infrastructure management, transportation planning, and safety analysis by providing up-to-date and detailed information on Wisconsin's public road bridges. The data is maintained under a public domain license as a work of the United States government, allowing unrestricted public use.本要素服务（Feature Service）提供美国威斯康星州境内公共道路桥梁的详细地理空间数据。该数据集源自美国联邦公路管理局（Federal Highway Administration, FHWA），属于美国交通部国家交通地图集数据库（National Transportation Atlas Database, NTAD）的组成部分。数据集的核心内容包括：全面的桥梁识别与分类信息，涵盖唯一结构编号及线路数据；桥梁结构特征，包含桥梁类型、长度、宽度、跨数及净空尺寸等参数；桥梁状况评估数据，涉及桥面、上部结构、下部结构及其他关键部件的评估结果；检测与维护记录，详细记载检测日期及检测频次；交通数据，涵盖日均交通量及货车占比等信息；桥梁所有权及养护机构相关信息。本数据集可为威斯康星州公共道路桥梁提供最新且详尽的信息，助力基础设施管理、交通规划及安全分析等工作的开展。本数据集作为美国政府作品采用公有领域许可协议进行维护，允许公众无限制使用。
