某线唐白河大桥为一座双线墩台单线架设12孔～31.7米预应力混凝土梁的全长402.32米的大桥。其中主河槽4孔,航运远期规划要求通行5000吨级轮船,因此原设计系架设2孔～64米下承钢桁梁。1959年施工时,当时缺乏大跨度钢梁,临时增建两个单线桥墩,改设4孔31.7米预应力混凝土梁作为过渡措施。1964年该线全线建成通车至
A line of Tangbaihe Bridge is a double-line piers abutment single-erected 12 holes to 31.7 meters of prestressed concrete beams 402.32 meters in length of the bridge. Among them, the main channel 4 holes, shipping long-term planning requires the passage of 5,000-ton ships, the original design of the system set up 2 holes to 64 meters under steel truss girder. In 1959 when the construction, the lack of long-span steel beams, the temporary addition of two single-line piers, the replacement of 4 holes 31.7 meters of prestressed concrete beams as a transitional measure. In 1964, the line was completed and opened to traffic
