Bridge Conditions, NYS Department of Transportation

New York State inspectors assess all of the bridges every two years including a bridge’s individual parts. Bridges are analyzed for their capacity to carry vehicular loads. Inspectors are required to evaluate, assign a condition score, and document the condition of up to 47 structural elements, including rating 25 components of each span of a bridge, in addition to general components common to all bridges. The NYSDOT condition rating scale ranges from 1 to 7, with 7 being in new condition and a rating of 5 or greater considered as good conditionBridges that cannot safely carry heavy vehicles, such as some tractor trailers, are posted with weight limits. Based upon inspection and load capacity analysis, any bridge deemed unsafe gets closed.

纽约州检查员每两年对所有的桥梁及其各个部分进行全面评估。桥梁的分析旨在评估其承载车辆荷载的能力。检查员需对至多47个结构元素进行评估，并赋予条件评分，记录其状况，包括对每座桥梁每一跨的25个组件进行评级，以及记录所有桥梁共有的通用组件的状况。纽约州交通厅（NYSDOT）的条件评分量表从1至7不等，其中7表示全新状况，评分达到5或以上被视为良好状况。无法安全承载重型车辆的桥梁，如某些拖拉机拖车，会被标注重量限制。基于检查和承载能力分析，任何被认定为不安全的桥梁将被关闭。
