Jersey Barrier maintained by King County Roads Division

For more information about this layer please see the GIS Data Catalog. A Jersey barrier or Jersey wall is a modular concrete or plastic barrier employed to separate lanes of traffic. It is designed to minimize vehicle damage in cases of incidental contact while still preventing the crossover case of a head-on collision. Jersey barriers are also used to reroute traffic and protect pedestrians during highway construction. Plastic water barriers of the same general shape are also now commonly referred to as jersey barriers.如需了解该图层的更多信息，请参阅地理信息系统（GIS）数据目录。泽西护栏（Jersey barrier）又称泽西墙，是一种模块化混凝土或塑料护栏，用于分隔交通车道。其设计旨在当车辆意外接触时最大程度降低车辆损毁程度，同时可防止车辆越道引发正面碰撞。在高速公路施工期间，泽西护栏还可用于交通导流以及保护行人。现如今，外形与泽西护栏大体一致的塑料注水护栏，也通常被统称为泽西护栏。
