美国的一些大型建筑，由于退离道路较远，为了缩短空间多巨离，更方便顾客或游人进出，采用了有硕的传送带通道，这种空间形式类似中国传统的长廊，而且高架于绿地，道路之上，称其为桥廊。桥廊一般长约百米，从路边的“亭”起始，或曲或直，跨越草坪、广场，一直通入室内大厅 Some large buildings in the United States, due to their long distance from the road, are more convenient for customers or visitors, in order to shorten the space and leave more space. The use of a large conveyor channel is similar to the traditional Chinese promenade and is elevated over green areas. Above the road, call it the bridge corridor. The bridge corridor is generally about one hundred meters long. Starting from the “kiosk” on the roadside, it may be curved or straight, crossing the lawn and square, and leading into the indoor hall.
