我家附近有一座特别的桥,它的名字叫什邡市三号洞子桥。这座桥桥下没有河流,更没有水,是一座简易的立交桥。桥的下面是一条水泥路,分左右两条分道,单行通过。每天我都看见许多车辆有序地通过这座立交桥,桥的上面是一条火车轨道,火车像一条长龙一样在上面飞驰着。立交桥的中心有一个高大粗壮的钢筋水泥制作的桥墩,它坚固结实,支撑着桥面,这座铁路公路立交桥的形状很像字母“M”。就是这座桥,连通了什邡市城里城外 There is a special bridge near my home, its name is Shibao No.3 Dongzi Bridge. There is no river under the bridge, there is no water, is a simple overpass. Below the bridge is a cement road, sub-divided into two, one-way through. Every day I see many vehicles passing through the overpass in an orderly manner. Above the bridge is a train track that runs like a long dragon. At the center of the overpass there is a tall, sturdy reinforced concrete piers that solid and support the bridge deck. The railroad overpass is shaped like the letter “M”. This bridge is connected to the city outside Shifang City
