一座比著名的武汉長江大桥還長一倍的郑州黃河大桥,将要在今年國庆节建成通車,这座大桥是去年5月開始动工的,原定1960年完成,現在将比原計划提前一年。 这是正在修筑中的北京广州鉄路复线的重大工程之一。我國解放前遺留下来的鐵路,大都鋪着輕重不同的鋼軌,路綫的弯道、坡度和桥梁的載重能力等等大都不合技术标准,因而行車速度慢,通过能力小。几年來,政府对这些鉄路進行了大規模的改造工作,大大 A Zhengzhou Yellow River Bridge, which is twice as long as the famous Wuhan Yangtze River Bridge, will be completed and opened to traffic this year on the National Day. The bridge began construction in May last year and was originally scheduled for completion in 1960. It will now be one year ahead of schedule. . This is one of the major projects of the Guangzhou-Guangzhou double-track line under construction. Most of the railways left before the liberation of China were covered with rails of different severity. The corners, slopes, and load capacity of the bridges of the routes were not all in line with technical standards. Therefore, the speed was low and the capacity was low. Over the past few years, the government has carried out large-scale reconstruction work on these roads.
