The urban system is a grid and every street on this city goes across the river on a pontoon bridge.

城市系统是一个网格，这个城市的每条街道都在一座浮桥上过河。

They practiced disaster water-surface helicopter rescue, debris and narrow-space rescue operations, and fast building of pontoon bridges against the backdrop of flooding, earthquake and other disasters.

此次演习包括洪水、地震等其他灾难情况下的水上救援、瓦砾及狭窄地域救援以及浮桥快速搭建等科目。

So the electricity poles go to little villages in the hinterland, the pontoon bridges are used in small towns, the material is all reabsorbed.

所以电线杆到腹地的小村庄，浮桥到小城镇， 材料全部重新吸收。
